Given:
The images of the graphs are given.
Required:
To find how the leading coefficients affect the shape of a parabola.
Step-by-step explanation:
When the value of the leading coefficient is positive then the parabola opens upwards and when the value of the leading coefficient is negative then the parabola opens downwards.
As the value of the leading coefficient is increased the graph to be skinnier or as the value of the leading coefficient decrease the graph to be wider.
In graphs 1 and 2, the parabola opens upwards so the coefficients A and B will be positive. In graphs 3 and 4, the parabola opens downwards so the leading coefficient
