Which of the following statements are true about the quadratic function f(x)=a(x-h)^2 + k that has no real zeros? Select all that apply.
(3 points)
The value of h cannot be zero.
The value of k cannot be 0.
If the value of k is negative, then the value of a is negative.
If the value of a is positive, then the value of k is negative.
If the value of a is positive, then the graph opens upwards.
The value of a must be greater than one, so the graph is vertically stretched.
The values of a and k must have opposite signs.
- The value of k cannot be 0.
- If the value of k is negative, then the value of a is negative.
- If the value of a is positive, then the graph opens upwards.
- The values of a and k must have opposite signs.
