f(x) = √x2 -6x + 9 (complete equation in square root) ~ Find the domain and the range. Share with your friends Share 0 Lovina Kansal answered this Dear student We have,f(x)=x2-6x+9We know f(x)⇒f(x)≥0So, x2-6x+9≥0x-32≥0x-3≥0 or x-3≤0 As fx2≥a⇒f(x)≥a or fx≤ax≥3 or x≤3So, domain of f is (-∞,∞)Range of f:f(x) can never take negative values.So, range of f is [0,∞) Regards 1 View Full Answer
