QuestionFind x-intercepts, y-intercept, domain, range of f(x)=x2+4xf(x) = x^2 + 4x, and graph the function.

Studdy Solution
olving for f()f(-) gives f()=4f(-) = -4. So, the range of the function is [4,)[-4, \infty).
In conclusion, the x-intercepts are x=0x =0 and x=4x = -4, the y-intercept is y=0y =0, the domain is (,)(-\infty, \infty), and the range is [4,)[-4, \infty).
