A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate. An equation that produces such a set of ordered pairs defines a function. What is the catch? There can be at most one output for every input.
We are given a coordinate (4,16).
Where first coordinate is the value of x and second coordinate is the value of y for the function y=f(x).
We need to find the value of given point (4,16) for function y= 0.5f(x).
Here function f(x) is being multiplied by 0.5.
On multiplying 0.5 by y, it will effect the value of y only. It does not effect value of x . Because x value is still x. Only function f(x) is being multiplied by 0.5.
Therefore, y= 0.5f(4) = 0.5 * 16 = 8.
So, (4,8) is the point on the graph of y = 0.5f(x) corresponds to (4, 16).
Answer:
x=14
Step-by-step explanation:
2 times x = 2x and 2 time 9 is 18 so the equation is 2x-18=10. then you add 18 to both sides and get 2x=28 then simplify to x=14
