To select from options the equation that correctly describes the graph.
Answer to Problem 16MCQ
Option D.
Explanation of Solution
Given information :
Option A.
Option B.
Option C.
Option D.
From the graph shown, it is evident that the vertex is at
The graph of a
This vertex point shall be:
Highest point (if
Or, lowest point (if
In this case, ‘a’ has to lesser than 0 hence the graph will have a maximum and will open downwards.
A parabola always points to infinity, either negative or positive.
Option B.
Option A.
Here, the graph is reflected across the x- axis but not translated as shown in the graph. Hence we reject this option.
Option D.
Here, the graph is reflected across the x- axis and translated upwards as shown in the graph. Hence, this equation is the one shown in the graph.
