Q. Find lim⁡x→−5h(x) \lim _{x \rightarrow-5} h(x) for\newlineh(x)=5x+4x+8.  h(x)=\frac{5 x+4}{x+8} \text {. }
  1. Identify the function: Identify the function whose limit we need to find.\newlineWe are given the function h(x)=5x+4x+8h(x) = \frac{5x + 4}{x + 8}.\newlineWe need to find the limit of h(x)h(x) as xx approaches −5-5.
  2. Substitute xx into function: Substitute the value of xx into the function to see if the function is defined at that point.\newlineLet's substitute x=−5x = -5 into h(x)h(x) to check if the function is defined at x=−5x = -5.\newlineh(−5)=5(−5)+4(−5)+8=−25+43=−213=−7.h(-5) = \frac{5(-5) + 4}{(-5) + 8} = \frac{-25 + 4}{3} = \frac{-21}{3} = -7.\newlineThe function is defined at x=−5x = -5, so we can directly substitute the value.
  3. Calculate the limit: Calculate the limit by substitution since the function is continuous at x=−5x = -5.lim⁡x→−5h(x)=h(−5)=−7\lim_{x \to -5} h(x) = h(-5) = -7.

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}}
