Answer:
1. y = 9(x+1/2)^2 -13/4
Step-by-step explanation:
y = 9x^2 + 9x – 1
first isolate the x terms
y = 9(x^2 +x) -1
then add 1/4 inside the brackets to make it a perfect square trinomial (half of the coefficient of the x term squared is how we get 1/4)
since we just added 1/4 we need to subtract what we just added to balance the equation. so 1/4 times 9 is 9/4 ( the number we just added to the equation). then you subtract 9/4 outside of the brackets.
y = 9(x^2 +x +1/4) -1 -9/4
then simplify
y = 9(x+1/2)^2 -13/4
If you are talking about $110 being increased by 140% then the answer is $264

Answer:
f(x) = 4x^2 -8x -32
Step-by-step explanation:
If "a" is a zero, then (x -a) is a factor. For some scale factor k, the equation can be written ...
f(x) = k(x +2)(x -4)
We want f(0) = -32, so ...
f(0) = -32 = k(0 +2)(0 -4) = -8k
4 = k . . . . . divide by -8
Then the factored equation is ...
f(x) = 4(x +2)(x -4)
Multiplying it out gives ...
f(x) = 4x^2 -8x -32
