Answer:
The given graph shows a function of x.
Step-by-step explanation:
Neither 1 nor 3 is a single-valued relation for some values of x. The graph shown passes the vertical line test, so does represent a function.
The graph is a relation that is a function of x.
___
The attached graph is of the equation of 3. A vertical line will intersect the graph in more than one place, so the relation is NOT a function.
We know that the graph of a function is a line that passes through the coordinates (2, 11) and (8, 14) and we must find the equation for the line.
1. We must use the next formula to find the slope
Where (x1, y1) and (x2, y2) are the points.
Now, replacing the points in the formula for the slope
2. We must replace the slope and one of the points in the next formula
Now, replacing the slope and the point (2, 11)
3. We must delete the parenthesis and solve the equation for y
