Which statement is true regarding the functions on the graph?
sergey [27]

Answer:

f(3) = g(3)

General Formulas and Concepts:

<u>Algebra I</u>

  • Reading a Coordinate Graph
  • Coordinates (x, y)
  • Solving systems of equations by graphing
  • Functions
  • Function Notation

Step-by-step explanation:

According to the graph, we see that both lines intersect at <em>x</em> = 3. Therefore, that means both lines at that <em>x</em> point will have the same <em>y</em> value. Both f(3) and g(3) would equal 6, leading us to the answer of f(3) = g(3).
