To solve a problem, we often the given information into algebraic expressions and equations.

Example: The phrase "4 more than twice a number" becomes '2n + 4'.

rewrite

Step-by-step explanation: 4 more than twice a number turning into 2n + 4 is a polynomial that was rewritten from the example

step-by-step explanation:

abc

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
