What effects does "h" have on the parent function?

• Vertical stretch/compression

• Horizontal shifts (left/right)

• Vertical shifts (up/down)

Which variable, when negative, can cause the parent function to reflect across the x-axis (face downwards)?

• a

• h

• k

Does the following quadratic equation have a maximum or minimum value? How can you tell?
y=x²+2x-3

• Minimum value, because the a value is positive

• Maximum value, because the b value is positive

• Maximum value, because the a value is positive

• Minimum value, because the c value is negative

Given the equation for this parabola:
