Answer:
x = -2
Step-by-step explanation:
f(x) = 2( x^2 +9x -5x - 45)
f(x) = 2(x^2 + 4x - 45)
f(x) = 2x^2 +8x -90
axis of symmetry formula: x = -b / 2a
x = -(8) / 2(2)
x = -8 / 4
x = -2
*you can also graph the equation on a graphing calculator and find the middle of the parabola
Step-by-step explanation:
step one f(x) Is a quadratic equation and
step two h(x) is a linear equation
