Is y=1/4xto the power of. 05a power function

Subject to conditions (see below), yes.

Step-by-step explanation:

The simplest power function looks like y = x^n, where n is the exponent. We often see power functions; they are integral parts of polynomial functions (such as y = x^3 + 3x^2 + x + 1).

IF you meant, "Is y = (1/4) x^0.05 a power function?" then the answer is "yes." It's important that you use parentheses around that fraction 1/4 for clarity.

y = (1/4) x^0.05 has a graph that is initially quite close to the horizontal line y = 1/4.

If you mistyped the question and you meant y=1/4x to the power of 0.5X then yes it's a function, but if you didint mistyped it then no because it cannot be graphed
