Question

Evaluate p(x)=−3+4x when x=−2,0, and 5.

Answer 1

p(-2) = -11

p(0) = -3

p(5) = 17

Explanation:

Think of p(x) as a y. Just substitute the x values into the equation, and with some basic algebra, you should get your answer

p(-2) = -3 + (-8) = -11

p(0) = -3 + 0 = -3

p(5) = -3 + 20 = 17
