-2[-1.8]+8
=-2×-1+8
=2+8
=10

Answer:

option c)10

Step-by-step explanation:

Given is a least integer function as

[tex]f(x) =-2[x]+8[/tex]

We are to find out the function value when x = -1.8

Substitute for x the value -1.8

we have

[tex]f(x) =-2[-1.8]+8\\[/tex]

-1.8 has the integer -1 to the left of it.

Hence we get

[tex]f(x) =-2[-1]+8=10[/tex]

Hence answer is option c)10
