# how to determine if an equation is a function calculator

Let's suppose "f" as a function and "b" as a continuous quantity (a real number), the equation as per limit formula would be as follows: \lim_ {x\to\ b} f \left (x \right) = \text {L} This illustrates that f (x) can be set as near to L as preferred by making x closer to b. In order to be a function of x, for a given x it has to map to exactly one value for the function. (iv) 12 / 28: the function should be y=2x+4 1/3 4 9. what does the data represent in the function? 1 3 7 / 18 Compute expert-level answers using Wolfram's breakthrough, algorithms, knowledgebase and AI technology, Solve linear, quadratic and polynomial systems of equations with Wolfram|Alpha, Partial Fraction Decomposition Calculator.

Suppose a diamond mining organization has used two inputs capital and labor in the production of diamonds. If the vertical line intersects the graph in more than one point, then the given graph does not represent a function. Mostly all mathematical formulas are expressions of known function. Sum and product of the roots of a quadratic equations Algebraic identities if x=1, This video explains how to determine if a given equation represents a function using the definition of a function. 1 2 "The equation for the function defines the rule by which the input value x … In algebra, a function is defined as an equation where it assigns exactly one output for the every given specified input. In case, if each input in relation has accurately one output, then the relation is called a function. Does any one know what the rule would be its a in n out table? The function is generally represented as f(x). 10/66 In this equation, C is total production cost, FC stands for fixed costs and V covers variable costs. Learn how to determine whether relations such as equations, graphs, ordered pairs, mapping and tables represent a function. The series will be a function of the parameters a and b, and the independent variable, x. Plotting the original y-data and the calculated result, “ycalc”, on the same graph tells us that the parameters of the function are not yet correct. If the vertical line intersects the graph in at most one point, then the given graph represents a function. Answer to: Determine whether the equation is an identity, a conditional equation or an inconsistent equation. The left and right limits must be the same; in other words, the function can’t jump or have an asymptote. (iii) 10/ 25 : the function should be y= 2x+5 The mathematical way to say this is that The graph of the function can be represented by calculating the x-intercept, y-intercept, slope value and the curvature value. The sunrise equation can be used to derive the time of sunrise and sunset for any solar declination and latitude in terms of local solar time when sunrise and sunset actually occur. 9 / 24. -2 / 4 Integral function differentiate and calculate the area under the curve of a graph. To avoid ambiguous queries, make sure to use parentheses where necessary. (iv) 7 / 18: the function should be y=2x+4 How To: Given two points on the curve of an exponential function, use a graphing calculator to find the equation. Next, we calculate a new series in Excel using the equation above. Once you've done that, refresh this page to start using Wolfram|Alpha. But here are the points: (0.00, 4.32) (0.25, 4.36) (0.50, 4.58) (0.75, 5.79) (1.00, 6.14) (1.25, 7.25) (1.50, 7.64) (1.75, 8.08), and (2.00, 8.14) XV.1.. Find a Green function such that if f is continuous, then the equation y = Gf provides a solution for L(y) = f, y(0) = y'(0) = 0, where L is as defined below. 3 / 6 4/12 … If x =14, then y= 2(14) +2 The domain of the function is 0,1, 2, 3, 4 Solving quadratic equations by quadratic formula. It is: ⁡ ∘ = − ⁡ × ⁡ where: ∘ is the hour angle at either sunrise (when negative value is taken) or sunset (when positive value is taken); is the latitude of the observer on the Earth; 2 / 4, x y (iii) 5 / 12 : the function should be y= 2x+2 One also learns how to find roots of all quadratic polynomials, using square roots (arising from the discriminant) when necessary. 0 0 The graph of a function is a graph of equations that have been solved for the variable “y”.
