Conjecture (fog)(x), if f(x)=13x-9 and g(x)=9x+13

(fog)(x) = 117x + 160

Step-by-step explanation:

∵ f(x) = 13x - 9

∵ g(x) = 9x + 13

∵ (fog)(x) means ⇒ f(g(x)) ⇒ g(x) is the value of x in of f(x)

∴ (fog)(x) = 13(9x + 13) - 9 = 117x + 169 - 9

∴ (fog)(x) = 117x + 160

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
