A, because it's based on whether or not they do their chores, and it's not for certain
X - distance between Jie and Xiaoqing.
Answer:
See below and attachment
Step-by-step explanation:
<u>Given function:</u>
<em>The graph is attached and the axis of symmetry and all the required points plotted </em>
a) Axis of symmetry:
b) It has no minimum as the leading coefficient is negative.
- Maximum value is at vertex- the point (3, 4).
- Maximum value is y = 4
c) and d) x - and y - intercepts already given in the question
e) Domain is all real numbers. x = ( -∞, +∞ )
Range is y = ( - ∞, 4]
2nd subtraction property.
6u + 3u = 18
9u = 18
u = 18/9
u = 2
