Question

Can anyone help me? I'm so lost on this question. thanks!! ​

Answer 1

Explanation:

This is a ‘piece wise function’ meaning it has different functions depending on the value of the independent variable, x.

So for questions a and b where x<-2 you sub the x value into the top equation, 5x-1.

f(-4)=5(-4)-1=-20-1=-21

f(-3)=5(-3)-1=-15-1=-16

Since the second two x values are not less than -2, you sub the x values into the second equation x-9

f(-2)=-2-9=-11

f(0)=-0-9=-9

Answer 2

a. -21

b. -16

c. -11

d. -9

Explanation:

if x is less than -2, then u have to use the equation 5(x)-1

if x is greater than or equal to -2, then you have to use the equation (x)-9
