Hello!
We can put in numbers for x to get points of the graph
2(-4)^2 + 16(-4) + 30 = -2
One point is (-4, -2)
2(-3)^2 + 16(-3) + 30 = 0
The next point is (-3, 0)
2(-5)^2 + 16(-5) + 30 = 0
The third point is (-5, 0)
The parabola has a vertex of (-4, -2) and goes through the points (-3, 0) and (-5, 0)
Hope this helps!
Answer:
9x2+3x−1=0
Step 1: Use quadratic formula with a=9, b=3, c=-1.
x=

Step 1: Replace f(x) with y: y=-8-5x
Step 2: Switch X and Y: X=-8-5y
Step 3:Solve for y: x+8=-5y ≈ y=(x+8)/-5
Step 4: Replace y with F^-1(x): f^-1(x)=(x+8)/-5 :)
