what is the y - intercept of the quadratic function $f(x)=(x - 8)(x + 3)$?\n(8,0)\n(0,3)\n(0,-24)\n(-5,0)
what is the y - intercept of the quadratic function $f(x)=(x - 8)(x + 3)$?\n(8,0)\n(0,3)\n(0,-24)\n(-5,0)
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 - 8)(0+3)\ &=(-8)\times3\ &=- 24 \end{align*} ] The y - intercept is the point ((0,f(0))), so it is ((0,-24)).
Answer:
C. ((0,-24))
