The change in temperature from last week to this week=3.5
Step-by-step explanation:
To get the change in temperature from last week to this week, we need to take last week's temperature and subtract it from this week's temperature.
For example;
Change in temperature=This week's temperature-last week's temperature
where;
This week's temperature=-2.25
last week's temperature=1.25
replacing;
Change in temperature=(1.25)-(-2.25)=1.25+2.25=3.5
The change in temperature from last week to this week=3.5
Answer:
The third graph
Step-by-step explanation:
The Greatest Integer function (also called "floor" function. is in fact the one depicted on your first graph on the left. It indicates the integer part of the real number x.
So, if one translates such function two units down , as requested by the subtraction of 2 of the function y the problem shows, one ends up with the third graph depicted on the page.
