Note that the from

to 0, that is the left part, the function is the line y=1.
Similarly, from 0 (not included) to

, the function is y=-1.
Thus the function is given by the rule:
y=1, for x≤0,
y=-1, for x>0.
Remark: a horizontal line at height c, from the x-axis, is the graph of the function y=c.
Answer:

Step-by-step explanation:
Cost of shirt normally = $65
Cost of shirt for 3 days =
× $65
=

= $39.33 (rounded to nearest cent)
Answer:
Step-by-step explanation:
<u>Simplify, rationalize the denominator</u>
- √2/(3 + √5) =
- √2(3 - √5)/(3 + √5) (3 - √5) =
- (3√2 - √10)/(3² - 5) =
- (3√2 - √10)/4
C will be the answer to the equation
