Question

which graph decreases, crosses the y-axis at (0, −7), and then increases? graph a graph b graph c text description for graph a. graph a b. graph b c. graph c

Explanation:

Step1: Analyze Graph A

Graph A first decreases, then becomes constant. It crosses the y - axis at (0, - 5) (not (0, - 7)) and does not increase after the constant part. So Graph A is not the answer.

Step2: Analyze Graph B

Graph B first increases, then becomes constant. It does not have a decreasing part first, so Graph B is not the answer.

Step3: Analyze Graph C

Graph C first decreases (from left to right, the line goes down), crosses the y - axis at (0, - 7) (by looking at the vertex of the V - shaped graph which is on the y - axis at y=-7), and then increases (the right part of the V - shaped graph goes up). So Graph C matches all the given conditions.

Answer:

C. Graph C
