6. Given the function rule f(x)=x^2-3x+2, what is the output of f(-2)?
A. -8
B. 0
C. 4
D. 12
7. Suppose you earn $15 for each car you wash. Which function describes the relationship between your total earnings E and and the number of cars you wash C?
A. E(c)=c+15
B. E(c)=15c
C. c=15E
D. E(c)=c-15
Can someone help me????
Can you help me with the other problem?
ms. Sue or anyone who is a stellar at math???
f(-2)=(-2)^2-3(-2)+2
=4+6+2=12....
E(c)=15E .......
Are you sure this is correct? This is a unit test and I don't want to get this wrong.
E(c)=15c sorry for my typo yes am sure
your fine and thanks so much for your help.
ill try it
Sure, I'd be happy to help you!
Let's start with question 6. To find the output of the function f(x) = x^2 - 3x + 2 when x = -2, we simply substitute -2 into the function and evaluate it.
So, f(-2) = (-2)^2 - 3(-2) + 2
= 4 + 6 + 2
= 12
Therefore, the output of f(-2) is 12. The correct answer is (D).
Now let's move on to question 7. The question asks for a function that describes the relationship between your total earnings E and the number of cars you wash C. Since you earn $15 for each car you wash, the function should represent that relationship.
In this case, the correct function would be E(c) = 15c. Here, E(c) represents your earnings (E) and the variable c represents the number of cars you wash. Since you earn $15 for each car, multiplying the number of cars (c) by 15 gives you your total earnings (E).
Therefore, the correct answer is (B) E(c) = 15c.
I hope that helps! Let me know if you have any more questions.
