The sum of four times a number and eight is between zero and twelve

Step-by-step explanation:

The sum of four times a number and eight is between zero and twelve

For example : x is between a  and b can be written as a<x<b

Now we frame inequality for the given statement

Sum of four times a number and eight

LEt the unknown number be x

four times a number is 4x

Sum of 4x  and 8 is

4x+8 lies between 0  and 12. So the inequality becomes

idk

step-by-step explanation:

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
