1) find f(x) if it is known that f(5a)=5a−2. 2) find g(x) if it is known that g(2t)=8t−1.

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

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
