If the question is, Is y = x4 an exponential function ? then the answer is no.
An exponential function is one where the variable appears as an exponent.
So, y = 4x is an exponential function.
That is a function. x=y^2 is not a function.
y = x This is a line and a function. Function values are y values.
determine whether each relation is a function y equals -8
no
y=x+2if y=66=x+26-2=x4=xso x=4
(x2 + y2)(x + y)(x - y) = x4 - y4.
Y=X^2 is a function for it forms a parabola on a graph.
If you plug in y for the x function, and it equals the answer you got, it is right.
y - |x| is an expression, not a function.
Yes.
Yes, it is.
Yes.
