Find the sum of -3x^2+5x-8 and -10x^2-x-3.

- 13x² + 4x - 11

Step-by-step explanation:

- 3x² + 5x - 8 - 10x² - x - 3 ← collect like terms

= - 13x² + 4x - 11

its 69.420

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
