if f(x)=-8x + 8 and g(x)= x-9,what is (f,g)(18)?

To find (f,g)(18), we need to evaluate the composition of the functions f(x) and g(x) at x = 18.
The composition of two functions, denoted as (f,g)(x), is defined as f(g(x)). In other words, we need to substitute g(x) into f(x) and evaluate the result at x = 18.
First, let's find g(18) by substituting x = 18 into g(x):
g(18) = 18 - 9 = 9
Next, substitute this value of g(18) into f(x):
f(g(18)) = f(9)
To evaluate f(9), substitute x = 9 into f(x):
f(9) = -8(9) + 8
= -72 + 8
= -64
Therefore, (f,g)(18) = -64.
f(x)=g(x)
n wht answer will come = 18
I hope u got it!!!
