This is the question ​

C

Step-by-step explanation:

over the interval [-1,1], f(x) is greater than 0

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
