Is y^8=3x-7 a function of x

If y⁸ is a function of x, that means that there cannot be more than one y value for each x value. You can test this by either doing the vertical line test, which requires you to graph the equation. To do this test, draw an imaginary vertical line anywhere on the graph. If the line crosses the curve at more than one place, it is not a function. Based on the graph (see below), this equation is a function of x.

If the exponential parent function,
laila [671]

Answer: f(x) =3^{-x}-4

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

If f(x)+k, the function is translated up "k" units.

If f(x)-k, the function is translated down "k" units.

If -f(x), the function is reflected across the x-axis.

If f(-x), the function is reflected across the y-axis.

Therefore, knowing those transformations and given the exponential parent function:

f(x) = 3^x

If it is reflected across the y-axis and the it is  translated down 4 units, we can determine that the resulting function is:

f(x) =3^{-x}-4
