Answer:
Yes
Step-by-step explanation:
Yes it is a function, because graph is intersecting y - axis only once.
To find the graph of f(x) = x^2 - 2x + 3, you can either plug in values into where the x variable stands and solve for their corresponding y-values or you can also use your graphing calculator or even Desmos works!
The mean is the average of a set of numbers. So to do that:
add all the numbers 120+235+98+142=$595
Then divide that by the total number in the set, in this case it is 4.
$595/4= $148.75 assuming that the prices given are the final price of the job.
