Sketch a graph of f(x): 4 on y axis and up 6
Identify the vertex: (4,6)
Identify the intervals where f(x) is increasing or decreasing: it increasing [6,00)
Thanks for your help:-)
No, the vertex is at (4,6)
The interval where f(x) is increasing is on the x-axis, or [4,oo)
f(x) increases from 6 upwards, but we talk about an interval in the domain, not the range.
