Concept explainers
a.
To select the option amongst the graphs that maps the given
a.
Answer to Problem 45PFA
Option B.
Explanation of Solution
Given information :
The give equation is
The given quadratic equation can be factorized to obtain the roots. The roots are plotted in the graph at the points where the curve intercept the x-axis.
Given equation.
Bifurcating the mid-term in order to obtain the roots.
Taking the common components.
These are the factors of the equation.
Hence, the roots are -3 and 2. Option B implies of a graph that passes through these points and hence is the answer.
b.
To select the options that have the roots of the given quadratic equation.
b.
