what is the y - intercept of the quadratic function $f(x)=(x - 6)(x - 2)$?\n(0,-6)\n(0,12)\n(-8,0)\n(2,0)
Answer
Explanation:
Step1: Recall y - intercept concept
The y - intercept of a function is found by setting (x = 0).
Step2: Substitute (x = 0) into the function
[ \begin{align*} f(0)&=(0 - 6)(0 - 2)\ &=(-6)\times(-2)\ &=12 \end{align*} ] The y - intercept is the point ((0,f(0))), so it is ((0,12)).
Answer:
B. ((0,12))
