Answer:

$f(-1) = -12$

Step-by-step explanation:

<u>Step 1: Set x to -1 and solve</u>

<u /> $f(x) = -3x^2+2x-7$

$f(-1) = -3(-1)^2+2(-1) - 7$

$f(-1) = -3(1) - 2 - 7$

$f(-1) = -3 - 2 - 7$

$f(-1) = -12$

Answer: $f(-1) = -12$

Which expression is equivalent to:1/m6

Valentin [98]

Answer:

Step-by-step explanation:

6 is a power. So both C and D are wrong because 6 is being treated as an ordinary integer.

So the answer must be either A or B.

B is not correct because to move an expression from the denominator to the numerator changes the sign in the base (which is m in this question).

A is correct. the power is changed from 6 in the denominator to -6 in the numerator. m is shifted to the numerator as well.
