Use the grapi un
18. the outside circle is dilated to the inside circle.
the circle is getting - and the scale factor is
a. smaller;
c. bigger; 2
b. bigger;
d. smaller: 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

the answer is 1030 it's very simple math.
