I'm assuming that you are given the equation f(x) = 2x^2 + 3 and the value f(-3).
To find this, all you need to do is plug in the value of -3 in f(x) for all x values. It would look like:

All you need to do is simplify:



Your final answer is f(x) = 21.
Hello!
Let's subtract the eight DVDs Joe received as gifts, because he didn't buy them on his own.
35 - 8 = 27
Now, divide the remaining CDs by the 3 years he collected his DVDs in.

A N S W E R:
Joe bought 9 DVDs last year.
Good day!
Change 30 hours into minutes, then divide by 20 and 25
Answer: I not super sure, but I think you are supposed to put the equations on each side of the table. Your end result should be 2x to the second -5x-3.
