HELP I NEED HELP ASAP HELP I NEED HELP ASAP HELP I NEED HELP ASAP HELP I NEED HELP ASAP
lozanna [386]

Answer:

Answer in explanation

Step-by-step explanation:

Before this we do this question let's get fimiliar with what's a function.

A function is a equation that when graphed, each input(x) correspond to one output(y). This means one inputs can't map to the diffrent output.

The vertical line test is just puting a vertical line anywhere on the function. If the vertical line touches more than two points your graph is not a function. If it touches one you graph is a function. The reason is because a vertical line that touches 2 points means one x maps to two diffrent y and thats not a function.

In conclusion the graph does pass the vertical line test so it is a function.

Hope this helped!,

Derivative of the following cos(x^{2} y)=y^{2}
MatroZZZ [7]

Answer:

\cos( {x}^{2}y )  =  {y}^{2}  \\  \frac{d( \cos( {x}^{2}y) ) }{dx}  =  \frac{d( {y}^{2}) }{dx}  \\ (2xy +  {x}^{2} \frac{dy}{dx}  ).( -  \sin( {x}^{2} y) ) = 2y \frac{dy}{dx}  \\   \frac{- 2xy \sin( {x}^{2}y )   -  {x}^{2}  \sin( {x}^{2} y) }{2y}  =  \frac{dy}{dx}  \\
