To select from options describing the relationship between
Answer to Problem 50PFA
Option C. In vertex form, the equation of the function is
Explanation of Solution
Given information :
Option A.
Option B.
Option C. In vertex form, the equation of the function is
Option D. In standard form, the equation of the function is
Option A.
It cannot be concluded from the graph if
Hence, cannot select option A. as the incorrect one.
Option B.
The graph of a quadratic equation (
This vertex point shall be:
Highest point (if
Or, lowest point (if
In this case, ‘a’ is lesser than 0 hence the graph will have a maximum and will open downwards.
A parabola always points to infinity, either negative or positive.
In the function
This is true for the graph shown. Hence, option B is eliminated.
Option C. In vertex form, the equation of the function is
The graph represented by
If
If
In the function
This is not true as the horizontal translation in graph shown is to the left.
Therefore, option C is selected as the correct answer.
