Answer:
The axis of symmetry for the graph of y = -2x² + 16x - 7 will be:
x = 4
Hence, the last option i.e. x = 4 is the correct option.
Step-by-step explanation:
Given the equation
For a parabola in standard form y = ax² + bx + c
The axis of symmetry is the vertical line that goes through the vertex x = -b/2a
so
The axis of symmetry for y = ax² + bx + c is x = -b/2a
In our case,
Therefore,
x = -16/2(-2)
x = -16 /-4
x = 16/4
x = 4
Therefore, the axis of symmetry for the graph of y = -2x² + 16x - 7 will be:
x = 4
Hence, the last option i.e. x = 4 is the correct option.
Answer:
The midpoint is (5/2, -15/2)
Step-by-step explanation:
The x coordinate of the midpoint is the average of the x coordinates
(1+4)/2 = 5/2
The y coordinate of the midpoint is the average of the x coordinates
(1+-16)/2 = -15/2
The midpoint is (5/2, -15/2)
