If you know f(x) is continuous, even and: f(t)dt=2 on the integral 0 to 2, f(t)dt=-1 on the integral 1 to 2, and f(t)dt=7 on the integral 2 to 4:

What is f(t)dt on the integral -1 to 2

What is f(t-1)dt on the integral 1 to 2

and what is the average value of f(x) on the interval [-4,4]

Thank you so much!
