Answer to Problem 49E
The x- intercepts of the graph of quadratic function
Explanation of Solution
Given data:
The given quadratic function is
Concept used:
The x-intercept (s) of the graph of a function
Calculations:
The graph of the function is shown in Figure-1.
We see that the graph of the quadratic function
Hence, the x- intercepts of the graphof quadratic function
Algebraically, the x-intercept (s) of the graph
Thus, the x- intercepts of the graph of quadratic function
Conclusion:
The x- intercepts of the graph of quadratic function
