Please give a detailed answer, I do not understand this. Thank you.

Question 3. Exponential functions can be used to model certain situations. For example, suppose you have the following data.
1
3 4
y 1.5 4.07 11.04 30 79
Part A. Plot the data on Geogebra. Just enter the points as coordinates, for example (0,1.5).
Part B. Do the points look like some sort of exponential function? You may need to zoom out.
Part C. Let's try to create a function that models the data. Let's suppose it looks like f(x) = a · b* . Find a and b by solving the system of equations fitting the
function with the data points (0,1.5) and (1,4.07) In other words, solve f(0) = 1.5 and f(1) = 4.07. HINT: THINK OF WHEN WE DID THE MODELING
PROBLEM WITH EXPONENTIAL DECAY
Part D. Plot your function. Is it a 100% match to the data? Why might there be error?
