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
Answer:
9x+3x=12x
180/12=15
9 x 15= 135
3 x 15= 45
135+45=180
x=15

There are 12 people who play tennis, but all of those 12 people also play football, so nobody only plays tennis.
<u>Answer: </u>
Tacos and Pizza both will be served on 12th day of school
<u>Explanation:</u>
Given, pizza is served in the school cafeteria every fourth school day.
And, on every 3rd school day Tacos are being served.
If both are served today then we have to find the number of days after which both will be served on the same day again.
Taking LCM of 4 and 3 to solve the question,
LCM of 4 and 3 = 4×3 = 12
Therefore, after 12 days both will be served on the same day.
