Find y if x=2 : a. y=7-(x) b. y= x to the power of 2 minus 1. c. y= x+14 cubed

steposvetlana [31]

Answer:

Step-by-step explanation:

y = 7 - x

y = 7 - 2

y = 5

y = x^2 - 1

y = (2)^2 - 1

y = 2*2 - 1

y = 4 - 1

y = 3

y = x + 14

I'm going to assume that you mean (x + 14)^3

y = (x + 14)^3

y = (2 + 14)^3

y = 16^3

y = 4096

If you really do mean what it says, then

y = 2 + 14^3

y = 2744 + 2

y = 2746

The graph of the equation x=y2+4is symmetric with respect to which of the following

lyudmila [28]

Answer:

The x-axis

Step-by-step explanation:

The graph of the equation x=y2+4 is symmetric with respect to the x-axis.

To test for symmetry with respect to the x-axis we substitute -y in place of y and simplify the equation. If the resulting equation is identical to original one then the function is symmetric with respect to the x-axis;

$x=y^{2} +4\\x=(-y)^{2} +4\\x=y^{2} +4$

which is identical to the original equation
