Does anyone know how to do this? !

B, C

Step-by-step explanation:

I am sure you have heard of the vertical line test. What the vertical line test does is make sure, for every, input, there is only one output. What this means is that two points cannot have the same x, unless they have the same y.

Two different x's can have the same y, but two different y's cannot have the same x.

In this problem, the x's that are taken by other coordinates with different y values are: 1, 3, 4, -4.

This means that the x you are trying to find cannot be any of those since the y value is different than all the other points. Which leaves you with the answers B and C.

Hope this helps, don't hesitate to ask more questions.

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

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
