FINDING FUNCTION VALUES FROM A GRAPH WORKSHEET

Question 1 :

Use the graph of f(x) shown below to find f(6).

Question 2 :

Use the graph of f(x) shown below to find f(9).

Question 3 :

Use the graph of f(x) shown below to find f(4).

Question 4 :

Use the graph of f(x) shown below to find f(4).

Answer 1 :

We have to find value of the function f(x) at x = 6.

Step 1 :

Draw a vertical line through 6 on the x-axis.

Step 2 :

Mark the point of intersection of the vertical line x = 6 and the graph of f(x).

Step 3 :

Draw an horizontal line from the point of intersection to y-axis.

Step 5 :

The horizontal line meets y-axis at 4.

So, the value of the function f(x) at x = 6 is 4.

That is, 

f(6) = 4

2. Answer :

We have to find value of the function f(x) at x = 9.

Step 1 :

Draw a vertical line through 9 on the x-axis.

Step 2 :

Mark the point of intersection of the vertical line x = 9 and the graph of f(x).

Step 3 :

Draw an horizontal line from the point of intersection to y-axis.

Step 5 :

The horizontal line meets y-axis at 7.

So, the value of the function f(x) at x = 9 is 7.

That is, 

f(9) = 7

3. Answer  :

We have to find value of the function f(x) at x = 4.

Step 1 :

Draw a vertical line through 4 on the x-axis.

Step 2 :

Mark the point of intersection of the vertical line x = 4 and the graph of f(x).

Step 3 :

Draw an horizontal line from the point of intersection to y-axis.

Step 5 :

The horizontal line meets y-axis at 7.

So, the value of the function f(x) at x = 4 is 7.

That is, 

f(4) = 7

4. Answer :

We have to find value of the function f(x) at x = 4.

Step 1 :

Draw a vertical line through 4 on the x-axis.

Step 2 :

Mark the point of intersection of the vertical line x = 4 and the graph of f(x).

Step 3 :

Draw an horizontal line from the point of intersection to y-axis.

Step 5 :

The horizontal line meets y-axis at 5.

So, the value of the function f(x) at x = 4 is 5.

That is, 

f(4) = 5
