Problems, once again.

1. Compute the average value of:

f(x} = x/(x+3) over the interval [-a,a]

2. Find the area of the region bounded by the graph of:

y = 2√(x^2 + 1)

X axis

Y axis

Line x = 1

On the first, integrate, then divide the integral by 2a.

On the second, integrate with respect to x from x=0 to x=1

INT y dx= INT 2√(x^2 + 1) dx
