Answer:
x = 9
x = 3
Step-by-step explanation:
find the roots of x² - 6x - 27 = 0
by factorization (or use any of your favorite methods for solving quadratic equations):
x² - 6x - 27 = 0
(x-9)(x+3) = 0
Hence,
(x-9) = 0 --------> x = 9
or
(x+3) = 0 --------> x = -3
The intercepts of the quadratic function is 9 and 3.
A function can be defined as a mathematical expression which explains the relationship between dependent variable and independent variable.
It always comes with a defined range and domain.
The function given in the question is
f (x) = x² - 6x - 27
To find the intercept means to find the roots of the equation
roots can be determined by
x² - 9x + 3x -27 = 0
x(x-9) -3(x-9) = 0
x= 9 , 3
Therefore the intercepts of the quadratic function is 9 and 3 .
