Question

Evaluate the function at each specified value of the independent variable and simplify. (If an answer is undefined, enter UNDEFINED.)

F(x) = {2x + 6, x<0
{9-x, x>0
(a) f(-2) =
(b) f(0) =
(c) f(1) =

Answer 1

Below.

Explanation:

(a) 2

`F(x)=2x+6\\F(-2)=-2(2)+6=2`

(b) Undefined, as 0 falls in neither parameter.

(c) 8

`F(x)=9-x\\F(1)=9-1=\fbox{8}`
