Question

If point 4,5 is on the graph of a function which equation must be true?a. f(5)=4 b. f(5,4)=9 c. f(4)=5 d. (5,4)=1

Answer 1

Here we are given that the point (4,5) is on the graph of a function.

Let us say the function is represented by f(x)

Now we have our coordinate given as (4,5).

here 4 is the x-coordinate and 5 is the y coordinate.

In a function f(x) =y , if we plug x coordinate in f(x), its value must be equal to the y coordinate.

So plugging the values of x and y,

f(5)= 4

So that is equivalent to our first option.

Answer: The function f(5)=y , (option a) represents the correction equation.

Answer 2

Answer:

The function f(5)=y , (option a) represents the correction equation.
