given the function rule f(x)=x^2-5x, what is the output of f(-3)
a 7
b -5
c 25
d 5
To find the output of f(-3), substitute -3 for x in the function rule:
f(-3) = (-3)^2 - 5(-3)
= 9 + 15
= 24
Therefore, the output of f(-3) is 24.
None of the given options match the result 24, so none of the listed options are correct.
To find the output of the function f(-3), we need to substitute -3 into the function rule f(x) = x^2-5x.
f(-3) = (-3)^2 - 5(-3)
Applying the order of operations, we first square -3:
f(-3) = 9 - 5(-3)
Next, we multiply -5 by -3:
f(-3) = 9 + 15
Finally, adding 9 and 15 together, we get:
f(-3) = 24.
Therefore, the output of f(-3) is 24.
