The graph of function f passes through (7,-1).

Function g satisfies f(g(x)) = x and g(f(x)) = x for all real numbers.

What point must the graph of g pass through?

What point must the graph of g pass through? Function f passes through (7,-1).

 

Hello Guest!

 

f(x) = x - 8

    x      |  -4    -3    -2    -1    0   1   2   3   4 

f(x) = z | -12 -11  -10   -9   -8  -7  -6  -5  -4

 

g(z) = z + 8

g(f(x))  |  -4    -3    -2    -1    0   1   2   3   4

 

Point (-7,1) must the graph of g pass through.
