Which of the following is the maximum value of the equation y=-x^2+2x+5 a. 5 b. 6 c. 2. d. 1

Answers

square root

step-by-step explanation:

answer: 15

step-by-step explanation:

 b. 6

Step-by-step explanation:

The maximum value is the y-value of the vertex.

Step 1: Find the x-value (aka Axis Of Symmetry) using the formula: x=\dfrac{-b}{2a}

x=\dfrac{-(2)}{2(-1)}=\dfrac{-2}{-2}=1

Step 2: input the x-value (above) into the given equation to solve for y:

y=-x^2+2x+5\\y=-(1)^2+2(1)+5\\y=-1 + 2 + 5\\y = 6
