which graph shows a function where f(2) = 4?
which graph shows a function where f(2) = 4?
Answer
Explanation:
Step1: Recall function - value meaning
The notation (f(2)=4) means when (x = 2), the (y) - value of the function is (4). So we need to find the graph where the point ((2,4)) lies on the curve of the function.
Step2: Check each graph
For the first graph, when (x = 2), (y\neq4). For the second graph, it is a parabola opening down - ward and when (x = 2), (y\neq4). For the third graph, when (x = 2), (y = 4). For the fourth graph, when (x = 2), (y\neq4).
Answer:
The third graph.
