WebJust like Transformations in Geometry, we can move and resize the graphs of functions Let us start with a function, in this case it is f (x) = x2, but it could be anything: f (x) = x2 Here are some simple things we can do to move or scale it on the graph: We can move it up or down by adding a constant to the y-value: g (x) = x2 + C WebAlgebra Graph f (x)=1/2x+2 f (x) = 1 2 x + 2 f ( x) = 1 2 x + 2 Rewrite the function as an equation. y = x 2 +2 y = x 2 + 2 Rewrite in slope-intercept form.

WebTo evaluate a function is to: Replace ( substitute) any variable with its given number or expression Like in this example: Example: evaluate the function f (x) = 2x+4 for x=5 Just replace the variable "x" with "5": f ( 5) = 2× 5 + 4 = 14 Answer: f (5) = 14 More Examples Here is a function: f (x) = 1 − x + x 2 f is just a name, WebQuotient Rule In calculus, the quotient rule is a method of finding the derivative of a function that is the ratio of two differentiable functions. Let h (x)=f (x)/g (x), where both f and g are differentiable and g (x)≠0. The quotient rule states that the derivative of h (x) is hʼ (x)= (fʼ (x)g (x)-f (x)gʼ (x))/g (x)². WebJun 30, 2016 · The required value of f(5) would be 22.4 when f(1) = 3.2 and f(x + 1) =5/2 which is an initial value condition.. What is the function?
