I'm having trouble with trying to solve this whoentire math problem from(a) through(d). Below.I have looked at the colored graph image and the other smaller image on the right side of that image shown and yet I still don't understand the problem solution to retrieve the current answer.

A survey approximates the number of Americans that are age 65 and older and projects that by the year 2050, approximately 83.2 million Americans will be at least 65. The bar graph shows the estimated number of Americans with projected figures for the year 2020 and beyond. A graphing calculator screen displays an exponential function that models the U.S. population age 65 and over, y, in millions, x years after 1899. Use this information to solve (a)-(d) below. Click the icon to view the bar graph. ExpReg y = a-b^x a = 3.4317029042 b = 1.023212685 a. Explain why an exponential function was used to model the population data. O A. An exponential function was used because there are too many data points to use a linear function. OB. An exponential function was used because exponential functions are always more accurate than linear functions. OC. An exponential function was used because population is always modeled using exponential functions. D. An exponential function was used because the data in the bar graph is increasing more and more rapidly. b. Use the graphing calculator screen to express the model in function notation, with numbers rounded to three decimal places. f(x) =

1 - Hey, can someone please help me with this math problem, I need help graphing it. Can you show me how to graph it exact because I keep getting people who just give me half’s. Example: 3.5, 2.5 Can you please put the dot on the line that is in the picture I cannot go in between the numbers so they have to be solid numbers corresponding to the graph that I provided. I’m really trying to leave this and some people are making it hard and confusing me
What’s the equations for these graphs?
