Which function has only one x-intercept at (-6, 0)?
f(x) = x(x - 6)
Of(x) = (x - 6)(x - 6)
f(x) = (x + 6)(x - 6)
f(x) = (x + 6)(x + 6)

f(x) = (x+6)(x+6)

Step-by-step explanation:

To find the x intercept you want each set of parenthesis to equal out to zero. Therefore to have an x intercept of only -6, then both sets of parenthesis must be (x+6) because -6 + 6 = 0.
