Sagot :

We have a piecewise function

if the value of x is less than zero the function will be 7x-10

if the value of x is equal to or greater than zero the function will be 7x-20

for the case x=-1, we will use 7x-10

[tex]f(-1)=7(-1)-10=-17[/tex]

for case x=0, we will use 7x-20

[tex]f(0)=7(0)-20=-20[/tex]

for case x=2, we will use 7x-20

[tex]f(2)=7(2)-20=-6[/tex]
