Question

if f(x)=[2x-1], find f(5.4)

Answer 1

f(x) = 2x - 1

f(5.4) = 2(5.4) - 1

f(5.4) = 10.8 - 1

f(5.4) = 9.8

hope this helps

Answer 2

you just have to plug in what x is, which they give you, to find the answer.

f(x) = 2x - 1
f(5.4) = 2(5.4) - 1
f(5.4) = 10.8 - 1
f(5.4) = 9.8

hope this helps, God bless!
