Question

P has degree 3 and zeros 4 and i.

Answer 1

(X+5)/2=1
x=-3

(Y+5)/2=4
Y=3

Point is (-3,3)

Answer 2

not solving for a point, solving for equation P(x)

Answer 3

Zeros are 4, i, and - i

(x - 4) (x - i) ( x - (-i)) = P(x)

(x - 4) ( x - i) (x + i) = P(x)

x^3 - 4 x^2 + x - 4 = P(x)

Answer 4

Q has degree 3, and zeros 0 and i

Answer 5

x(x-i)(x+i)= x^3+x?
