Part a· 3 steps
Will the function have a minimum or maximum?
Identify the coefficient of the term.
For the function , the coefficient of is .
Determine if the parabola opens upwards or downwards.
Since is negative (), the parabola opens downwards.
Conclude whether it's a minimum or maximum.
A parabola that opens downwards has a highest point, which is a maximum.
The function will have a maximum.
Part b-1
Determine the x-coordinates of the turning point.
Use the formula for the x-coordinate of the turning point (vertex) of a parabola .
The formula is .
From the function , we have and .Substitute the values of and into the formula.
The x-coordinate of the turning point is .
Part c25
Determine the y-coordinates of the turning point.
Substitute the x-coordinate found in part b) into the original function .
We found .
Calculate the value of .
The y-coordinate of the turning point is .
