Perform the indicated operation. (a^(2)-7a-18)/(4a^(3))-:(a^(2)-4a-4 5)/(2a^(3)-4a^(2))*(a^(2)+3a-10)/(a ^(2)-4a+4)=

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

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
