Rewrite the expression in the form 9^n. 9 x 9^2=?

n = 3

9 times 9^2 is 9^3, in this case n, the exponent is 3, so n = 3.

it is true

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
