Answer:
Domain of the given function is all real numbers and the range of the function all real numbers.
Step-by-step explanation:
The given function is
.... (1)
The slope intercept form of a line function is
.... (2)
Where, m is slope and b is y-intercept.
From (1) and (2), we get
It means the slope of the line is -5 and y-intercept is 4.
Draw a line with slope -5 and y-intercept 4 on a coordinate plane as show below.
Domain is the set of inputs and range is the set of outputs.
The function is defined for all values of x. So, the domain of the function is all real numbers.
The value of function can be any real number. So, the range of the function is all real numbers.
Therefore, the domain of the given function is all real numbers and the range of the function all real numbers.
Given claim: A coin favors heads when tossed, and there are
90 heads in 100 tosses.
Answer: There isn’t sufficient evidence to support this
claim, because the coin is a fair coin.
Given claim: Movie patrons have IQ scores with a standard
deviation that is less than the standard deviation of 15 for the general
population. A simple random sample of 40 movie patrons result in IQ scores with
a standard deviation of 14.8.
Answer: Claim is either true or false
In a rare event rule, <span>we conclude that the
assumption is probably not correct, if, under a given assumption, the
probability of a particular observed event is exceptionally small. </span>
You can use Desmos to graph these and make your own judgment as to the intercepts and rates of increase/decrease.
The ones with a base < 1 will decrease rapidly, then slowly. The one with a base > 1 will increase slowly, then rapidly. The y-intercept is the multiplier in front of the base.
F(x)=2x-4 because the y-int is -4 and it’s going up two each time and over one so 2/1 or just 2x
