Select the correct answer.
Which graph represents the equation below?

c

Step-by-step explanation:

we can see that the "a" value is -1, written as just "-" meaning the parabola is going to face down, this eliminates A and D, then if we solve for the x intercepts, ( set the values in the parenthesis equal to 0) we see that the intercepts are negative one and positive 3

b. astronomers

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
