Find the range of the function y=-x^2-3x when the domain is {-5,0,2}

umka21 [38]

Answer: $\{-10, 0 \}$

Step-by-step explanation:

The range is the set of output values for the domain (the set of inputs).

When x=-5, y= $-(-5)^{2}-3(-5)=-10$ .
When x=0, $y=-0^{2}-3(0)=0$ .
When x=2, $y=-2^{2}-3(2)=-10$

So, the range is $\boxed{\{-10, 0 \}}$

Answer:

Line a. goes to table 3, line b. goes to table 2, and line c. goes to table 1.

Step-by-step explanation:

Here are the 3 lines graphed (I even labeled each for you) so you can have a bit of a visual.

Hopefully you can find the points on each graph.

(Hint: The x row represents the x coordinate of an ordered pair, and the y row represents the y coordinate of an ordered pair.)

Ordered pairs look like this btw (x,y)

Hope this helps :)

<span>Water flows into a tank according to the rate F of t equals the quotient of 6 plus t and the quantity 1 plus t , and at the same time empties out at the rate E of t equals the quotient of the natural log of the quantity t plus 2 and the quantity t plus 1 , with both F(t) and E(t) measured in gallons per minute. How much water, to the nearest gallon, is in the tank at time t = 10 minutes</span>
