If g(x) = √(x-7) , find g(8), g(32) and g(80).

Question

If g(x) =
`√(x-7)` , find g(8), g(32) and g(80).

Answer 1

pafff

g(x)=
`√(x-7)`


this means if you put in 8 for x then you will get g(8)=
`√(8-7)= √(1)=1`

so subsitute and solve

g(8)=
`√(8-7)= √(1)=1  or -1`


g(32)=
`√(32-7)= √(25)=5 or -5`


g(80)=
`√(80-7)= √(73)=` aprox 8.544 but √73 would be acceptable
