When you multiply a function by -1 what is the effect on its graph?
vlada-n [284]

Answer:

Step-by-step explanation:

Depends on what you mean by multiplying by - 1.  I assume you are not going to multiply the y or f(x) term by - 1.

If that is so, take an example. Suppose you have a graph that is y=x^2

That's a parabola that opens upwards and it has a line going through its focus which is a point on the +y axis.

When you multiply the right hand side by - 1, the graph you get will be y = - x^2.

That opens downward and the focus is on the - y axis.

That means that the effect of the graph is that it flips over the x axis, which I think is the third answer.

Simplify 6-12b divided by 3a-6ab
siniylev [52]

Answer:

\frac{2}{a}

Step-by-step explanation:

Given

\frac{6-12b}{3a-6ab} ← factor both numerator and denominator

= \frac{6(1-2b)}{3a(1-2b)} ← cancel common factor (1 - 2b) on numerator/denominator

= \frac{6}{3a} ← cancel 6 and 3 by 3

= \frac{2}{a}

MATH HELP!?
Debora [2.8K]
<span><u><em>The correct answers are: </em></u>
 1) C
 2) A
 3) D

<u><em>Explanation</em></u><span><u><em>: </em></u>
1) <u>Voluntary deductions</u> are amounts that you elect to come out of your paycheck every pay period. Federal tax is not voluntary; neither is state tax, nor Social Security. The only voluntary deduction in this list is health insurance. You are not obligated to pay for your health insurance by automatically withholding it from your check.

 2) <u>FICA</u> is the tax that goes towards Social Security and Medicare. It is involuntary, and it is deducted as a percentage of your gross (pre-withholding) pay.

 3) <u>A fixed expense</u> would be one that is the same from month to month. The only one of these expenses that would be the same amount monthly is a mortgage.</span></span>
