Answer:

7. No, because the x-value 11 has two y-values pair with it.

8. Not a function

Step-by-step explanation:

If there is more than one y-values per x-value then it is not considered a function, same with Question 8.

Given z1 = -3
trasher [3.6K]

Answer:

See explanation

Step-by-step explanation:

The given complex number are:

z_1=-3\sqrt{3}+3i

and

z_2=6\cos 150\degree+6i\sin 150\degree

When we rewrite z_1=-3\sqrt{3}+3i in complex form, we obtain;

z_1=r(\cos \theta+i\sin \theta)

where

r=\sqrt{(-3\sqrt{3})^2+3^2 }=\sqrt{36}=6

and

\theta=tan^{-1}(\frac{y}{x})

\implies \theta=tan^{-1}(\frac{-3\sqrt{3}}{3})=150\degree

Hence,

z_1=6(\cos 150\degree+i\sin 150\degree)

z_1=6\cos 150\degree+6i\sin 150\degree

Hence

z_1=z_2

F(x)=2x-1 and g(x)=x^2
Fofino [41]

2x-1=x^2

If you plug these two equations into a graphing calculator, like desmos.com, you can see that the two lines will intersect at (1, 1).
