In three sentences or less, describe how we evaluate a function.
A brief definition of a straight line graph is a linear function of the form y = mx + c, where c and m are constants. Although you do not actually see the function written out, many professions use a straight line graph.
Name one profession that use a straight line graph and tell how it is used.

f(7) = 10x + 5x - 4

f(3a) = 2(3a) -2(3a) + 4
y = 3x + 1

4x + 2y = 16
Where x is 2
f(x) = x² - 2

Where x is 6
f(x) = 2x-10
F(x)=5(x)+5-10
F(6)
F(9)
Create an equation of a nonlinear function and provide two inputs to be evaluated.
