Answer:
Affects the steepness of the graph
Explanation:
A quadratic is in the form ax^2 + bx + c and is usually a parabola.
Changing the constant a will influence the gradient of this parabola and will therefore affect how steep it is.
If a is positive, the parabola will have a minimum turning point meaning that it will be facing upwards.
if a is negative, it will have a maximum turning point and face downwards.
