Solve for the area (A) of a rectangle if the length (l) is 4x and the width (W) is 5x*. Remember Area = length x width

If area = length * width that means the answer is 4x * 5x = 20x².

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
