C: Cubic Expression!

Step-by-step explanation:

In this equation/expression, you can look at the highest exponent which is 3, and you can also look at how many terms it has, which is 3. This makes it a 3rd degree trinomial, which makes it C, Cubic Expression!

Cubic Expression

Step-by-step explanation:

See answer above

at home andrea has 1 2/3 kilograms of rice

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
