Use the graph of the function to evaluate f(2)

 The correct option is (D) 2.

Step-by-step explanation:  We are given to use the graph to find the value of f(2).

From the graph, we see that

the value of y co-ordinate is 2 when the value of x co-ordinate is 2.

So, the point (2, 2) lies on the graph of the given function f(x).

Therefore, the value of f(2) is 2.

Thus, the required value of f(2) is 2.

Option (D) is CORRECT.

the answer would be  

a.

3: 1

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
