Which of the following functions is graphed below?

A                                                                                                                                                                                                                                                                                      

The answer is C

Step-by-step explanation:

A filled in dot means the inequality is less than or equal to or greeater than or equal to and since the slope is positive, the inequality is greater than. For the parabola, the dot is not filled in, so the inequality is less than.

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
