Compare the functions f(x) = x7 and g(x) = 7x by graphing both functions in several viewing rectangles. (a) Find all points of intersection of the graphs correct to one decimal place.
( 1, 2) (smaller x value)
( 3, 4) (larger x value)
I cant seem to find the points when i put it in my calculator. any help?
An obvious solution is a whole number that lies somewhere between 5 and 8 ....
The other solution solution cannot be found exactly. A decimal approximation lies somewhere between 1 and 2. You need to use your graph (or graphs) to estimate the value correct to 1 decimal place.
As to why you can't find the intersection points when you put it into your calculator, you should check:
1. that you've entered the correct equations.
2. you're using an appropriate window (check that ymin and ymax of the window are OK).
I was able to find the smaller, but not larger. any help?
