Fx) - (x+4) What is the equation of this function after it is reflected over the x-axis?
A. F(x) = -(x+4)
B. F(x) = -(y + 4)3
C. F(x) = y(x+4)3
D. F(x) = (y+4)

idk

step-by-step explanation: i just don't

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

there are infinitely many solutions.
