Question

Can I get some help and a walk through on this

Answer 1

a) -4/3

b) 8

c) -2/3

d) 2

Explanation:

In all four cases replace the value of "x" in the function's expression, and evaluate to find the numerical answer:

a)
`f((1)/(4)) = (1)/((1)/(4)-1 ) =(1)/((1)/(4)-(4)/(4)  )= (1)/(-(3)/(4) ) = -(4)/(3)`

b)
`g((1)/(4) ) = (1)/((1)/(4) ) +4 = 4 + 4 = 8`

c)
`f(-(1)/(2)) = (1)/(-(1)/(2)-1 ) =(1)/(-(1)/(2)-(2)/(2)  )= (1)/(-(3)/(2) ) = -(2)/(3)`

d)
`g(-(1)/(2) ) = (1)/(-(1)/(2) ) +4 = -2 + 4 = 2`
