Q. How does g(x)=8xg(x)= 8^x change over the interval from x=3x = 3 to x=4x = 4?\newlineChoices:\newline(A) g(x)g(x) increases by 800%800\%\newline(B) g(x)g(x) decreases by 88\newline(C) g(x)g(x) increases by 8%8\%\newline(D) g(x)g(x) increases by a factor of 88
  1. Calculate g(33): Calculate g(3) g(3) .\newlineg(3)=83 g(3) = 8^3 \newlineg(3)=512 g(3) = 512
  2. Calculate g(44): Calculate g(4) g(4) .\newlineg(4)=84 g(4) = 8^4 \newlineg(4)=4096 g(4) = 4096
  3. Find the ratio: Find the ratio g(4)g(3) \frac{g(4)}{g(3)} .\newlineg(4)g(3)=4096512 \frac{g(4)}{g(3)} = \frac{4096}{512} \newlineg(4)g(3)=8 \frac{g(4)}{g(3)} = 8
  4. Determine the change: \newlineSince the ratio is 88, g(x) g(x) increases by a factor of 88.

Question
Jill bought a used motorcycle from a seller online for $1,200. The seller will charge her $5 a day to store the motorcycle at his house until she is able to pick it up. You can use a function to describe the total amount of money Jill will owe the seller if she waits xx days to pick up the motorcycle.\newlineWrite an equation for the function. If it is linear, write it in the form g(x)=mx+bg(x) = mx + b. If it is exponential, write it in the form g(x)=a(b)xg(x) = a(b)^x.\newlineg(x)=‾g(x) = \underline{\hspace{3em}}
