Answer to Problem 2E
The last option is the different one.
The axis of symmetry is
The maximum value of the function is 32.
Explanation of Solution
Given information: The quadratic function
Formula used: x coordinate of vertex is
Calculation:
Let’s analyze each option.
When it says the maximum value of a function, it represents the y-coordinate of vertex which is ‘k’.
For open down parabola the greatest range is the y-coordinate of the vertex, which is ‘k’
The third option direction says y-coordinate of vertex ‘k’.
The last option says the x coordinate of vertex ‘h’ that would be our axis of symmetry.
So, last option is the different one.
Let’s find both answers.
x coordinate of vertex h=
From the function
Plug in these values into the formula,
Substitute back x as 2 into f(x) which gives value for k.
The axis of symmetry is
The maximum value of the function is 32.
