Exercise 74 Page 303

Calculate the function's value when by substituting - 2 for x in the equation.

- 11

Practice makes perfect

Using the function f(x), we want to evaluate for the given value, f( -2). To do this, we need to substitute -2 for x in each instance of the x-variable.

f(x)=4x-3

x= -2

f( - 2)=4( -2)-3

a(- b)=- a * b

f(-2)=-8-3

Subtract term

f(-2)=-11
