Can someone please help. Will you graph the functions and approximate an x-value in which the exponential function surpasses the
polynomial function. In your final answer, include a copy of the graph.
y = 2x^2 + 7
y = 5^(x-4)
y = 2x^2 + 7
y = 5^(x-4)
1 answer:
The best way to solve this is to simply graph both functions in excel or on paper up to an x value of about10. I have done this in excel and can demonstrate that the exponential function surpasses the polynomial function at about x = 8. You can quickly prove this by substituting x = 8 into both equations. It is very apparent from the graph attached.
