Complex numbers are numbers that have both imaginary and real number parts. Imaginary numbers occur when you take the square root of negative numbers. Here are some examples of imaginary numbers:

and

Real numbers are just normal numbers.

Complex numbers can be expressed generally in the form:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
