F(-1) f(x) = -3x2 + 2x - 7
egoroff_w [7]

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

If -1 &lt; x &lt; 0 which of the following has the smallest value?
Katyanochek1 [597]

Answer: (B) x^3

Explanation:

If you compare the graphs of

  • y = x^2
  • y = x^3
  • y = x^4

all on the interval -1 < x < 0, you'll find that y = x^3 is the smallest when x = -1

Squaring a negative number leads to a positive result, and similarly that happens with x^4 as well. This is because x^4 = (x^2)^2.

Plugging x = -1 into x^3 leads to y = -1 as a result.

The library has DVDs on crime, adventure and science fiction.
kozerog [31]

Answer:

The library has 1,056 crime DVDs.

Step-by-step explanatiion:

Crime : Adventure : Science

11x       :        6x       :   10x

6x+384=10x

384=4x

x=96

The number of crime DVDs is 11x.

We found that x=96.

So, the number of crime DVDs the library has is equal to 11*96.

11*96=1,056.

Hope this helps!
