I'm assuming the given function is f(x) = 15x^2 + 10x.
If so, then,
f(x) = 15x^2 + 10x
f(x) = 15*(x)^2 + 10*(x)
f(-1) = 15*(-1)^2 + 10*(-1) ... note how x is replaced with -1
f(-1) = 15*(1) + 10*(-1)
f(-1) = 15 - 10
f(-1) = 5
Therefore the answer is 5
9.25%
3.70/40= 0.0925
0.0925x100= 9.25%
I don’t see any of the problems so I’m guessing you would have to rewrite it
Step-by-step explanation:
my personal opinion is that the answer is 20
