Answer:
Step-by-step explanation:
One
f(5a) means that wherever you see an x, you put in 5a
x = 5a
f(x) = x/5t * 5t - 2
f(x) = x - 2
===============
Two
g(2t) = 8t - 1
x = 2t
g(x) = 8t/2t*x - 1
g(x) = 4x - 1
1)for the first one you can put a=(1/5)a in the function and it will be:
[tex]f(a) = a - 2[/tex]
so in a function , alphabet is not important and you can rewrite it to this:
[tex]f(x) = x - 2[/tex]
2)the same as the first , we can put t=(1/2)t and conclusion is :
[tex]g(t) = 4t - 1[/tex]
and then change the t to x:
[tex]g(x) = 4x - 1[/tex]
