What is the Graph function?

The graph of a function f is the set of all points inside the aircraft of the shape (x, f(x)). We can also define the graph of f to be the graph of the equation y = f(x). So, the graph of a character is a unique case of the graph of an equation.

How does Graph function?

For graphing functions, we need to plot its asymptotes, its x and y-intercepts, holes, and some factors on it by means of building a desk of values. Then simply join the factor by not touching the asymptotes and maintaining a observation of the area and range of the characteristic.

Lauren is saving money for a new tablet. The tablet costs $80. She has $17 so gar. What percent of her goal has she saved so far?

Answers

You have to set up a proportion:
17/80 = x/100
17 x 100 = 1700
1700/80 = 21.25
21.25%
If Lauren has to get $80 and only has $17 she has 17/80. 17 divided by 80 is 0.2125. To convert decimals to percents, you move the decimal over to the right 2 times. Your answer is 21.25

Ok I just did a test on this and my teacher taught me how to do it, For problem like number 3 with the table of numbers, You take the first to sets like -1,-5 and 1,1....Then   you do 1 - (-5) =  your answer then 1 - (-1) = your answer than you get 6 and 2  ...you want to divided those numbers 6/2 = 3 and that is positive so #3 is positive.                                                                                                                       Same thing for #4  1,-2 and 2,-6       -6 - (-2) = x      2 - 1 = x  x/x  I want you to solve #4 for yourself        #2 is already done  y = -4x + 5  just take the -4 and -4 is negative so #2 is negative.   Then #1  I have a hard time with those but I think it's positive
