If p(x) = x2 - 1 and (x) = 5(x-1), which expression is equivalent to (p – 9)(x)?
5(x - 1) – x2 - 1
(5x - 1) – (x2 - 1)
(x2 - 1) – 5(x - 1)
(x2 - 1) – 5x - 1

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

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
