Answer:
Yes
Step-by-step explanation:
f(x) = x³ − 9x² + 11x + 21
f(3) = (3)³ − 9(3)² + 11(3) + 21
f(3) = 27 − 81 + 33 + 21
f(3) = 0
Answer:
Step-by-step explanation:
Given
Reflection across y-axis
Required
Find C'
For reflection across y-axis, the rule is:
So, the image of C is:
Hence:
The origin is at 0 on the x-axis and 0 on the y-axis. The intersecting x- and y-axes divide the coordinate plane into four sections. These four sections are called quadrants. Quadrants are named using the Roman numerals I, II, III, and IV beginning with the top right quadrant and moving counter clockwise.
(4 2/3) / (4 1/5) = 1.111
