Question 145242: I have two problems I need assistance with. I just need to know how to solve the questions.
1. if y=e with an exponant of 4 then In y= ?
2. find the rate of change of y, when y=30 + 4x, over the interal x=2 to x=4?

1. y=e%5E4
ln+y+=+ln+e%5E4++

ln+e%5Ex+=+x
ln+y+=+ln+e%5E4+=4+

2. Find the rate of change of y, when y=30 + 4x, over the interal x=2 to x=4.

Rate of change of y is actually the "slope" of the curve at a given point. In this case, you have a straight line with slope 4. This is the rate of change. Final answer = 4.
