F - 12 = -35
f - 12 + 12 = -35 + 12
f = -23
Percent is 480% and the decimal is 2.8
The surface area of a sphere is

and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0.
For example, let us assign values.
Let A=90
A= 90*9 = 810

and

the first r is 2.68 and the second r is 8.03
then,

or rounded off to 3.
Step-by-step explanation:
Let's look at A(x) and see how it is different from f(x)
- it is shifted downwards by 8 units
- it is not shifted to the left or the right
Therefore A(x) = f(x) - 8
Let's look at B(x) and see how it is different from f(x)
- it is not shifted downwards or upwards
- it is shifted to the left 7 units
Therefore B(x) = f(x + 7)
Let's look at C(x) and see how it is different from f(x)
- it is shifted upwards by 4 units
- it is shifted to right by 5 units
Therefore C(x) = f(x - 5) + 4
Let's look at D(x) and see how it is different from f(x)
- it is not shifted downwards or upwards
- it is not shifted to right by 12 units
Therefore D(x) = f(x - 12)
