The function f(x) = x^2 + 6x + 5 is a quadratic function, and Brianna should use -1 and -5 as the x-intercepts of the function
What are x-intercepts?
The x-intercepts of a function are the points where the function crosses the x-axis
The function is given as:
f(x) = x^2 + 6x + 5
Expand the function
f(x) = x^2 + x + 5x + 5
Factorize the function
f(x) = (x +1)(x + 5)
Set to 0
(x + 1)(x + 5) = 0
Solve for x
x = -1 and x = -5
Hence, Brianna should use -1 and -5 as the x-intercepts of the function
