Answer:
f(6) =6^2 - 2(6)
f(6) = 36 - 12
f(6) = 24
f(-3) = (-3)^2 - 2(-3)
f(-3) = 9+6
f(-3) = 15
f(-4) = (-4)^2 - 2(-4)
f(-4) = 16 + 8
f(-4) = 24

Consider the following Argand-diagram
enter image description here
The y-axis is the imaginary axis and the x-axis is the real one. The complex number in question is
x+yi
To figure out θ, consider the right-triangle formed by the two-coordinates on the plane (illustrated in red). Let θ be the angle formed with the real axis.
tanθ=yx
⟹tan−1(yx)
The hypotenuse of the triangle will be
x2+y2−−−−−−√
Therefore,
Step-by-step explanation:
