Evaluate the function
insens350 [35]

Answer:

Step-by-step explanation:

For a. you are asked to evaluate f(0).  This is a piecewise function with different domains for each piece of the function.  You can only evaluate f(0) in the function that has a domain that allows 0 in it.  In the first domain, it says

x < -3.  0 is not less than -3, so 0 is not in that domain, so you will not use that "piece" of the function to evaluate f(0).

In the next domain, it says that x is greater than or equal to -3 and less than 0.  Again, 0 is not included in that domain, so we can't use that "piece" of the function to evaluate f(0).

The last domain says that x is greater than OR EQUAL TO 0, so this is where we evaluate f(0):

f(0) = -0 - 4 so

f(0) = -4

When we want to evaluate f(2), we follow the same rules.  Find the piece of the function that allows 2 in its domain.  That's the middle piece:

f(2) = 2(2) - 6 so

f(2) = -2

I don’t get it! It says “Match each division expression to it’s quotient.” So can anyone help with 1/12 / 1/6 ? Please!
natta225 [31]

We have two fractions being divided. When we divide two fractions, we flip the second fraction and multiply

1/12 divided by 1/6 = 1/12 * 6/1

-------

From here we multiply straight across.

The numerators multiply to get 1*6 = 6

The denominators multiply to 12*1 = 12

We end up with 6/12 which reduces to 1/2 when you divide both parts by the GCF 6

<h3>Final Answer:  1/2</h3>
