1. what is the average rate of change of the quadratic function from
x = -3 to x = 2? f(x)=x^2+3x−2
just type in the numeric answer.

2. what is the vertex of the graph of

f(x)=x^2+10x−9?

3. how many solutions does the following quadratic function have?

−8x^2+2x−7=0

4. find the discriminant.

6q^2+8q−3=0

1. The average rate of change of a function over an interval is given by the difference quotient

Here,

2. Complete the square to rewrite the quadratic in vertex form:

which indicates its vertex occurs at the point (-5, -34).

3. Check the discriminant. For a quadratic polynomial , the discriminant is

Because the discriminant is negative, there are two complex roots.

4. Same as before:
