Write the given polynomial in standard form and write its degree . y³+2y(y-y³)+5y²+5y+15.
If necessary simplify.
​

In Standard form it is -2y^4 + y^3 + 7y^2 + 5y + 15.

Degree 4.

Step-by-step explanation:

y³+2y(y-y³)+5y²+5y+15

= y^3 + 2y^2 - 2y^4 + 5y^2 + 5y + 15

= -2y^4 + y^3 + 7y^2 + 5y + 15

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
