Answer: f(3)=-20

Step-by-step explanation:

If you look at f(x) and f(3), you can see that 3 is in place of x. That means when x=3, what is f(x). You plug in x=3 into f(x) and solve.

f(3)=-2(3)²-2

f(3)=-2(9)-2

f(3)=-18-2

f(3)=-20

shtirl [24]
Well that would be 105 - 10. If you spent 105 minutes in total and 10 of that was putting your stuff away, take that 10 minutes away and you’d get 95. So, she spent 95 minutes washing 3 cars in total. If you divide that 95 into 3s, you get rounded 31 minutes each.
