@chosenmatt

OpenStudy (chosenmatt):

yes?

OpenStudy (anonymous):

do you mind helping me with my math

OpenStudy (chosenmatt):

no

OpenStudy (anonymous):

\[f(x)=-5x ^{5}-4x+2\]

OpenStudy (anonymous):

what are you asked to do?

OpenStudy (anonymous):

What is the resulting ordered pair if the value of the independent variable is –1?

OpenStudy (anonymous):

-1

OpenStudy (chosenmatt):

okay good job @((*-*))

OpenStudy (anonymous):

Okay, the independent variable is the x, and the dependent variable is y. It depends on what x is , right?

OpenStudy (anonymous):

So you are asked to find f(-1), basically.

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

can you find f(-1).

OpenStudy (anonymous):

no I can't

OpenStudy (anonymous):

\[f(x)=-5x^2-4x+2\] to find f(-2), for instance, you would plug in -2 for x, into the function. Like this: \[f(-2)=-5(-2)^2-4(-2)+2\]\[f(-2)=-5(4)+8+2\]\[f(-2)=-20+8+2\]\[f(-2)=-10\]

OpenStudy (anonymous):

Can you find f(-1) now? (just plug in -1 instead of x, into the function, f(x) .

OpenStudy (anonymous):

ummm

OpenStudy (anonymous):

I'll set you up.\[f(-1)=-5(-1)^2-4(-1)+2\]

OpenStudy (anonymous):

continue....

OpenStudy (anonymous):

yed continue
