The path of a foam ball shot from a toy gun can be described by the equation Ax) = -x + 4x + 7, where f(x) is the height of the foam ball and x is the number of seconds
=
that have passed since the toy gun's trigger was released. Which of the following points
shows the extremum for the function?

answer: add the !

step-by-step explanation: then we will answer

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
