What value of b completes f(x)=2x^2+bx+74

282 6/7 cm^2

step-by-step explanation:

answer: i think it is (1,-2)

answer: it's upside down and i can't read it

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
