Which of the following are characteristics of the graph of the quadratic parent function? a. it has one intercept. b. it opens down. c. it has a vertex at (0, 0). d. it is u-shaped.

The correct options are A, C and D.

Step-by-step explanation:

The quadratic parent function is

The properties of quadratic parent function are:

1. It has one intercept, i.e, x- and y-intercept are at origin.

2. It has a vertex at (0, 0).

3. It is U-shaped.

4. Each image y has two preimage, except 0.

5. It opens up.

From the given option one the option B is incorrect because the quadratic parent function opens upward.

Therefore the correct options are A, C and D.
