Question

The value, in dollars, of an antique has increased exponentially over x years as shown in the graph below Part A: Estimate the y-intercept of the function. What does the intercept represent in this context?Part B: What are the domain and range of this function?Part C: Why are the x-values nonnegative?

Answer 1

The value, in dollars, of an antique has increased exponentially over x years as shown in the graph:

Part A: y-intercept of the function

`y-\text{intercept = \$1000}`

The intercept represents the constant value

Part B: The domain and range of this function:

`\begin{gathered} \text{domain}=(0,+\infty) \\ \text{range = }(1000,+\infty) \end{gathered}`

Part C: The x- values are non - negative because they are representing the ages of antique
