To identify the correct answer: Which of the following graphs is the accurate graph of the loan balance?
The answer is Graph (b).
Given information:
Interest rate: Twice
Explanation:
The graph of the present value is an exponential that has been reflected vertically and horizontally. It has the generic form
The graph of Carlos' balance will be the graph of the present value subtracted by the graph of the balance. If
Would be the graph of the balance, which means we have reflected about the
As long as
The curve may become sharper or softer depending on the interest rate (as happens when we change the base of the exponential), but the characteristics will be the same.

- Consider the graphs of y = f(x) and y = g(x) in the given diagram y= f(x). y = g(x) Evaluate (f+g)(2) -5 Determine all for which g(x) < f(x) Determine all for which f(x) +3 = g(x)arrow_forwardI) For what value(s) of x does g(x) = -4? Separate multiple answers with commas as needed. J) Give the interval(s) of such that g(x) > 0. Use the union symbol between multiple intervals. K) Give the interval(s) of such that g(x) <0. Use the union symbol between multiple intervals.arrow_forwardneed help on Barrow_forward

The concentration of a drug in a patient's bloodstream h hours after it was injected is given by 0.17 h Ah= h²+2' Find and interpret lim A(h). Remember, the answers to word problems should always be given in a complete h→00 sentence, with proper units, in the context of the problem.arrow_forward#2arrow_forward
