given the function rule f(x)=x^2-5x, what is the output of f(-3)
a 7
b -5
c 25*****
d 5
thanks
right you are.
Suppose you earn $12 each time you more than once which function describes the relationship between your total earnings E, and the number of times you mow the lawn M.
EM equals M +12
M equals 12 e
EM equals M -12
EM equals 12 m
The correct function that describes the relationship between total earnings E and the number of times you mow the lawn M is:
E = 12M
Well, let's find out! To calculate f(-3), we plug in -3 for x in the function rule:
f(-3) = (-3)^2 - 5(-3)
Now we simplify:
f(-3) = 9 + 15
So, the output of f(-3) is 24.
But wait, that's none of the options you provided! Looks like none of the given options are correct. Could it be a trick question? Maybe it's time to have a little chat with the person who came up with these options...
To find the output of the function f(-3), you need to substitute -3 for x in the function rule f(x) = x^2 - 5x.
So, replacing x with -3:
f(-3) = (-3)^2 - 5(-3)
Now, simplifying the expression:
f(-3) = 9 + 15
f(-3) = 24
Therefore, the output of f(-3) is 24.
None of the given answer options match the correct output of 24.
