Explanation of Solution
Given information :
The function
A quadratic equation would always form a graph that is a parabola. In this context, the vertex of the parabola would be in the origin only if the function is in the form of
Here ‘a’ is the coefficient of

b.
Answer to Problem 42HP
The given statement is always true.
Explanation of Solution
Given information :
The reflection of the graph of
The reflection of a function over the x-axis can be derived by multiplying the original function by -1. This means that the signs before the various variables and constants would be reversed. By doing this, there will be a reflection of the parent graph over the x-axis.
However, since the numeric value of the coefficients do not change, the width would remain unaltered.
