IMPOSSIBLE
If: x3+1 = 65 Then: x3 = 65-1 And: x3 = 64 So: x = 4 by means of the cube root function on the calculator
y = x2 is an (approximately) U shaped graph that is entirely above the x axis and is symmetric about the y axis. y = x3 is asymptotically negatively infinite when x is negatively infinite and positively infinite when x is positively infinite. It is symmetric about the line x+y=0.
no
Y=X^2 is a function for it forms a parabola on a graph.
Yes, y = -x3+1 is a function. You can graph it and see that it passes the vertical line test. See related link, below.
IMPOSSIBLE
No, it is not.
determine whether each relation is a function y equals -8
y = x This is a line and a function. Function values are y values.
If: x3+1 = 65 Then: x3 = 65-1 And: x3 = 64 So: x = 4 by means of the cube root function on the calculator
y = x2 is an (approximately) U shaped graph that is entirely above the x axis and is symmetric about the y axis. y = x3 is asymptotically negatively infinite when x is negatively infinite and positively infinite when x is positively infinite. It is symmetric about the line x+y=0.
no
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.
Y=X^2 is a function for it forms a parabola on a graph.
(a) y = -3x + 1
