Answer:
C
Step-by-step explanation:
There has to be two variables it's being compared to, in which case this is the blood sugar level and the amount of sugar
Okay, so first you make f(x) = y and switch x and y. So the equation becomes:
x = y^2 - 16
The next step is to get y by itself. So first you add 16 to both sides:
x + 16 = y^2
Now you square root everything, so the final answer is going to be:
the square root of x + 4 = y
15·0.8 + x = 30·0.9 --> x = 15
C. is the correct answer
