Calc 1 question

[soft plover]

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

You're integrating f(x), it would seem

It's never defined to be a specific function, you can only use the equations you're given and integral properties

ok so from $\int_{a}^{b}cf\left(x\right)dx=c\int_{a}^{b}f\left(x\right)dx$
c will be 20

and for b $\int_{a}^{b}f\left(x\right)dx=\int_{b}^{a}f\left(x\right)dx$ will be -9

is that right?

[jolly agate]

how would i do a tho

[obtuse agate]

with a, you have the integral property
$\int_a^b f(x)dx + \int_b^c f(x)dx = \int_a^c f(x)dx$

cute rizzly bear (won't eat you)

[obtuse agate]

you can chain them together

[plain slate]

$\int_{a}^{b}f\left(x\right)dx=-\int_{b}^{a}f\left(x\right)dx$
