Answer:
<u>Multiply</u> <u>3</u> on both sides.
Step-by-step explanation:
Subtract 22 on both sides so that the positive 22 can be canceled out and that the variable and one other number is left.
You should then get this equation:
Since there is division involved in 
, multiply both sides by three (Hint: Opposite of division is multiplication!) so that 3 would cancel out and that only the variable f is left.
× ×
You should get this equation now:
×
Solving it will let you have:
To check if your answer is right, replace the variable f with -15 in and solve.
Answer:
The vertex is y=-4
Step-by-step explanation:
The vertex is the minimum point of the graph of the quadratic equation.
Let's first find the like of symmetry.
dy/dx=2x+12
2x+12=0
2x=-12
x=-6
Now plug -6 into the quadratic equation
y=(-6)²+12(-6)+32
y=-4
