Answer:
g(x) = x^2/16
Step-by-step explanation:
To stretch a function horizontally by a factor of k, replace x with x/k.
You want a stretch factor of 4, so your function is ...
g(x) = f(x/4) = (x/4)^2
g(x) = x^2/16

The attached graph shows the horizontal stretch.
72 ÷ o should be the algebraic expression.
0.06 x 0.5 = 0.03 (I think that is what you're asking)
