According to the table, f(x) = 9 when x = -5. So if g(x) is the inverse of f(x), it follows that g(9) = -5.
By the inverse function theorem,
Just put it in a calculator!
276/11
25.09090909....
The answer is 25.09 repeating
Hope this helps!
Odd integers are 2 apart
the 3 consecutive odd numbers are x,x+2, x+4
sum is x+x+2+x+4 or 3x+6
the sum is 15 more than 2 times middle one
3x+6=15+2(x+2)
3x+6=15+2x+4
3x+6=19+2x
minus 2x both side
x+6=19
minus 6 both sides
x=13
x+2=15
x+4=17
they are 13,15,17
