Which of the following does not represent the function f(x)=2x+3

1 answer:

5 0

C is incorrect.
While the slope is 2, (calculated by rise over run), the y intercept is incorrect. The equation 2x+3 is written in slope intercept form (mx+b where b is y intercept). Therefore we can tell that 3 should be the y intercept. The y intercept on the graoh, however, is -3.

Answer:

B. Subtract 7

Step-by-step explanation:

You always want to isolate the x term to solve for x in any equation. Therefore, we need to move the 7 to the other side. Only way to do that is to subtract 7 on both sides.
