Since the point (9, 7) is on the graph of y = f(x), the sum of coordinates of that point is 29/4 or 7.25.
In Mathematics and Geometry, a function defines and represents the unique relationship that exists between two or more variables in a relation, table, ordered pair, or graph.
Since the point (9, 7) is on the graph of the function, f(x), and the value of x equals 9/2, we have the following;
f(2·x) = f(2 × 9/2)
f(2·x) = f(9)
f(2·x) = 7
2·y = (f(2·x)/2) + 2
2y = (7/2) + 2)
2y = 5.5 or 11/2
y = 5.5/2 or (11/2)/2
y = 2.75 or 11/4
Therefore, the coordinates (x, y) of the point are (11/4, 9/2)
Now, we can determine the sum of the coordinates of the point as follows;
Sum = 11/4 + 9/2
Sum = 29/4 or 7.25
Complete Question:
Given that the point (9,7) is on the graph of y=f(x), there is one point that must be on the graph of 2y=(f(2x)/2) + 2. What is the sum of coordinates of that point?
