Answer 1

y=x and ???

Answer 2

oops! y = x and y = 2sqrtx

Answer 3

something missing... y=x & what else? what is the boundaries? x=[0,?]

Answer 4

got it! give me sec

Answer 5

that better :)

pi [S] x^2 - 4x dx from some interval lol

Answer 6

x^3/3 - 2x^2

Answer 7

x=[0,4]

Answer 8

x = 2sqrt(x)

x^2 = 4x

x^2 - 4x = 0

x = 4/2 +- sqrt(16)/2

x = 2 +- 2; so o to 4
