Question

If g(x) = 4x - 4^x, what is the value of g(3/2)?

Answer 1

g(x) = 4x - 4^x

so

g(3/2) = 4(3/2) - 4^3/2

g(3/2) = 6 - 32

4^3/2 = -26

Answer 2

`g(x)=4x-4 ^( x)`

`g( (3)/(2))=4( (3)/(2))-4^{ ((3)/(2)) }`

`g( (3)/(2))=6- \sqrt[2]{4^(3) }`

`g( (3)/(2))=6- √(64)`

`g( (3)/(2))=6-8`

`g( (3)/(2))=-2`
