How do I solve this problem?

Step-by-step explanation:

The first 2 pieces of this function agree at pi/4, so we will set them equal to each other and sub in pi/4 for x to solve for k:

and

and we'll multiply everything by 16 to get rid of the fractions. Doing that gives us:

and

so

k = 3.067

The next one is a bit tricky if you're not up on your natural log equations.

Again, we set these equal to each other because they meet at the value of e. We sub in e for x and solve for m:

We'll sub in e for x. ln of e to the x power is equal to x, so

e + 2 = me and

so

m = 1.736

Hope that helps!
