Question

If f(x) = -2[x] + 8, what is f(-1.8)?
O 4
O 6
O 10
O 12

Answer 1

12

Explanation:

since the function is -2x+8 and you have been told to find f(-1.8) you have to replace -1.8 were there's x in the function.

f(x)=-2x+8

f(-1.8)=-2x+8

=-2(-1.8)+8

=3.6+8

=11.6 round off to 12

I hope this helps

Answer 2

10

Explanation:

Don't look at the other persons' answer, its wrong. The answer is 10 because I retook the quiz 3 TIMES until I got the right answer because the other people couldn't provide the right answer. All in all, I wish you all luck on your quiz and I hope you get it right! <3
