Graph k(x)=2x2+8x+9 on the Cartesian plane to the right. To graph the function you'll first have to plot the vertex (high/low point), then any other point.
k(x) is increasing on the interval(s):
k(x) is decreasing on the interval(s):
k(x) has a maximum of at x =
k(x) has a minimum of at x =
The domain of k(x) is:
The range of k(x) is:
If any of the above do not exist, enter DNE in the appropriate box(es).
Enter your answer using interval notation. Example: [2,5) Use U for union to combine intervals. Example: (-oo,2] U [4,oo) Enter each value as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 2^3, 5+4) Enter DNE for an empty set. Use oo to enter Infinity.
