Which expression can be used to find the area of a circle with a diameter of 40 cm?
a. 3.14 x 20
b 3.14 x 40
c 3.14 x 20 2
d 3.14 x 40 2

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
