- If the value of a is positive, then the graph opens upward.
- If the value of k is negative, then the value of a is negative.
Which of the following statements are true about the quadratic function f (x) = a(xh)² + k that has no real zeros? Select all that apply.

The values of a and k must have opposite signs.
If the value of a is positive, then the graph opens upward.
If the value of k is negative, then the value of a is negative.
The value of a must greater than one, so the graph is vertically stretched.
The value of k cannot be 0.
The value of h cannot be zero.
If the value of a is positive, then the value of k is negative.
