Question

1. 2x+8+9x^2+89/232
2. Cos(234)
3. integral of x^2
4. antiderivative of 5x^3+8x^2

Answer 1

Below...

Step-by-step explanation:

(9x^2 + 2x + 97) / 232

-0.766044443118978

(x^3) / 3 + C, where C is the constant of integration

(5/4)x^4 + (8/3)x^3 + C, where C is the constant of integration
