Find an equation for the polynomial p(x)

with y−
y

intercept at (0,45)
(

,
45
)
and roots: 3 (of multiplicity 2), 5, 1,-2

Step-by-step explanation:

The equation of a polynomial has the factored form as:

Since the roots here are 3, 5, 1, and -2, you take the opposite sign and place it in the equation. Where multiplicity is used this is the exponent of the factor.

To find a, plug in the point (0,45) and solve for a.

So the final equation is

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
