Question

Given the function: f(x)={(3x-4,x<0),(3x-8,x>=0):} Calculate the following values: f(-1)= f(0)= f(2)=

Answer 1

Below in bold.

Explanation:

f(x)={(3x-4,x<0),(3x-8,x>=0):

f(-1):

3x - 4 applies here as -1 is less than 0, so it is

3(-1) - 4

= -7.

f(0):

3x -8 applies:

So, f(0) = 3(0) - 8

= -8.

f(2):

= 3(2) -8

= -2.
