HELP PLEASE! Thank you!

1. First choice

2. Image C

3. Fourth chioice

4. Third choice

5. First choice.

Step-by-step explanation:

Solve the equation.

Use the difference of two squares formula.

A linear relationship already says it all. Find the graph that is NOT a curve. The only image that is not a curve and the graph straight forwards is the Image C aka A choice.

A nonlinear function is a function that does not have a straight line graph. All linear functions are linear, except for Quadratic and up. Every polynomial function with the degree greater than one wont be a linear.

If we change the constant from 3 to 5 then we would get

The graph would shift up 2 units.

The second and third graph both are function. We can tell by doing a line test. Simply draw a vertical line first. Then we check if the line intercepts the graph more than a point or not.

If the line intercepts more than a point then it is not a function.

If the line intercepts only a point then it is a function.

is it i think
