f(x) = x² + 2x + 12. Find the value when x=5 | Substitute the value x = 5 in the equation. f(5) = 5²+ 2(5) + 12 = 25 + 10 + 12 = 47

Graph the function y = f(x) = x² - 1 | Find the values of y with the corresponding values of x as follows: x = 0, then y = -1 : x = 1, then y = 0 : x = -1, then y = 0

The Square Root of a number | The number that when squared (x^2) is equal to the original number of the problem. Ex. 2² = 4, Therefore, √4 = 2

Linear Function Fact | The graph of a linear function is a non vertical line
🗑
|
||||
An equation such as, y = function (x) | If x is squared, cubed, or raised to any power except 1, the function is NON LINEAR.
🗑
|

Nonlinear Function Fact | The graph of a non linear function is not a straight line
🗑

-f(x) | Reflects f(x) over the x-axis
🗑
|

f(-x) | Reflects f(x) over the y-axis
🗑
