Exercise 7 Page 125

To evaluate a function for a given value of the variable, substitute the value for the variable.

-11, -3, and 17

Practice makes perfect

To evaluate a function for a certain value of x means that we substitute the given value for every instance of x. Let's do this for the given function when x=-2.

p(x)=-3+4x

Substitute

x= -2

p( -2)=-3+4( -2)

MultPosNeg

a(- b)=- a * b

p(-2)=-3+(-4 * 2)

Multiply

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

AddNeg

a+(- b)=a-b

p(-2)=-3-8
