This question is based on the value of calculation. Therefore, for x = 2, f(x) is equal to g(x).
Given:
f(x) = 9x + 7
g(x) = [tex]\bold{5^x}[/tex]
We need to determined the solution of the equation f(x) = g(x) for different value of x.
Now for x = -2 . we calculated the value of f(x) and g(x).
f(x) = 9(-2)+ 7 = -11
g(x) = [tex]\bold{5^{-2}}[/tex] = 0.04
Thus, for x = -2, f(x) is not equal to g(x).
Now for x = -1 . we calculated the value of f(x) and g(x).
f(x) = 9(-1)+ 7 = -2
g(x) = [tex]\bold{5^{-1}}[/tex] = 0.2
Thus, for x = -1, f(x) is not equal to g(x).
Now for x = 0 . we calculated the value of f(x) and g(x).
f(x) = 9(0)+ 7 = 7
g(x) =[tex]\bold{5^{0}}[/tex] = 1
Thus, for x = 0 , f(x) is not equal to g(x).
Now for x = =1 . we calculated the value of f(x) and g(x).
f(x) = 9(1)+ 7 = 16
g(x) = [tex]\bold{5^{1}}[/tex] = 5
Thus, for x = 1, f(x) is not equal to g(x).
Now for x = 2 . we calculated the value of f(x) and g(x).
f(x) = 9(2)+ 7 = 25
g(x) = [tex]\bold{5^{2}}[/tex] = 25
Thus, for x = 2, f(x) is equal to g(x).
Therefore, for x = 2, f(x) is equal to g(x).
