Question

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

Answer 1

Answer:

12

Step-by-step 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
