Find the x intercept of the graph of the equation -2(x+1)^2 +18

Burka [1]

Answer:

x=2, -4

Step-by-step explanation:

The equation is $y=-2(x+1)^2 +18$ . The x-intercept is the point(s) where the function intersects the x axis, so this value can be found by plugging in 0 for y. doing so results in $0=-2(x+1)^2 +18$ . Then, solve for x by moving 18 over, dividing by -2, square rooting both sides, and subtracting 1 to find the value of x.
