To calculate: The opening of the graph of function.
Answer to Problem 1QR
The graph of the function
Explanation of Solution
Given information:
The function is
Concept used:
The sign of the leading coefficient of the function decides whether the graph open upwards or downwards, if the sign is positive then the graph will open upwards and if the sign is negative then the graph will open downwards.
Calculation:
The function is
Algebraic Method:
The sign of the leading coefficient is negative.
So, the graph of the function opens downwards.
Graphical Method:
The graph of the quadratic function is a parabola.
So, the graph of the function is as shown below.
Conclusion:
The quadratic function opens downwards and it has been verified algebraically and graphically.
