The graph is continuous.
A continuous graph is depicted with straight smooth lines and not plot points as in a scatter graph. On the other hand, discrete graphs represent values at specific points along the number line. The most common discrete graphs are those that represent sequences and series. Since, these discrete graphs do not possess a smooth continuous line, they rather have plot points above consecutive integer values, unlike some continuous line graphs.
b) It is better to use a line graph where x values represent the weight in pounds and the y values represent the cost.
c) f(x) = 2.69 + 0.48(x-1)
d) domain is the x values; range is the y values
The function can be written out f(x) = 1.99x + 3.
Express the value of f(x) for x = 0.
This would cancel out the slope, giving us a horizontal line on (0, 3).
f(0) = 1.99(0) + 3
f(0) = 3
You can try to graph the function using a software or by hand.
The graph is continuous because the x-values can have any input as a point.
if x = 2 you have to find x to finish the problem
