Answer:
x = -1 and y = 6
Step-by-step explanation:
using x = -b/2a
x = -4 / 2(2)
x = -1
y = 2(-1)² + 4(-1) + 8
y = 2 - 4 + 8
y = 10 - 4
y = 6

Answer:

Step-by-step explanation:
We have been given that
and
. We are asked to find the expression that represents length of PS.
We know that
.
Upon substituting our given values in above equation, we will get:




Therefore, the expression
represents length of PS.
Answer: 5
----------------------------------------------------------
On the curve, the highest point has a y coordinate of y = 6
The lowest point on the curve has a y coordinate of y = -4
Subtracting the y values gets us: 6 - (-4) = 6 + 4 = 10
Cut that result in half: 10/2 = 5
The amplitude is 5. This is the vertical distance from the midline (y = 1) to either the highest point or the lowest point.
