Functions Worksheet 4 1. Let g(x)=−5x+2. Evaluate each of the following: (a) g(−1) (b) g(−2) (c) g(0) (d) g(5) 2. Let f(x)=2x+2. Evaluate each of the following: (a) f(−3) (b) f(6) (c) f(−1) (d) f(4) 3. Let g(x)=x2 +4x−1. Evaluate each of the following:

By evaluating functions, we determine what output (or “y-value”) the function produces for a given input (or “x-value”). Understanding how to evaluate functions is crucial in various fields such as mathematics, physics, economics, and engineering.

Evaluating Functions p.42 f(x) = y example If x is the independent variable and y is the dependent variable, then... f(x) = 4x - 3 essential question How do I use function notation to evaluate functions? To find f(x), simply substitute the value of x in parenthesis everywhere you see an x. 1.Evaluate f(x) = 4x - 3 when the domain is {-1, 2} 2.
