A square root of a number a is a number y such that y2 = a; in other words, a number y whose square (the result of multiplying the number by itself, or y⋅y) is a.[1] For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16. Every nonnegative real number a has a unique nonnegative square root, called the principal square root, which is denoted by √a, where √ is called the radical sign or radix. For example, the principal square root of 9 is 3, denoted √9 = 3, because 32 = 3 • 3 = 9 and 3 is nonnegative. The term whose root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this example 9.
x-intercepts are points of the form (x, 0), and y-intercepts are points of the form (0, y).
You find the x-intercepts by solving for x such that y = f(x) = 0:
You know x - 6 is a factor of f(x), which means x = 6 is a solution to the above equation, and that means that (6, 0) is one x-intercept.
You can find the other two by dividing f(x) by x - 6 (i.e. further factorizing f(x)).
So we have
and this means the x-intercepts are (6, 0), (2, 0) and (1, 0).
The y-intercept is easier to find; set x = 0, then solve for y = f(0):
and so the y-intercept is (0, -12).
