Question

I need help question 4

Answer 1

-51

Explanation:

If the limits are reversed, then place a negative sign in front of the integral.

`\int\limits^a_bf ({x}) \, dx =-\int\limits^b_a f({x}) \, dx`

`\int\limits^a_3 f({x}) \, dx = 51\\` where
`\alpha =10\\`

`\int\limits^3_\alpha f( {x}) \, dx =-51` where
`\alpha =10`
