Math Problem Statement

Graph the following function on the axes provided f(x)= (3x +14 for x < -5 x-4 for x > 2

Solution

To graph the function f(x)f(x), we need to break it down into its piecewise components:

Function Definition:

  • f(x)=3x+14f(x) = 3x + 14 for x<5x < -5
  • f(x)=x4f(x) = x - 4 for x>2x > 2

Steps:

  1. Graph for x<5x < -5:
    The equation is f(x)=3x+14f(x) = 3x + 14.

    • This is a straight line with slope 3 and y-intercept 14.
    • Since we are only interested in values where x<5x < -5, we'll start from that point and move to the left.
  2. Graph for x>2x > 2:
    The equation is f(x)=x4f(x) = x - 4.

    • This is a straight line with slope 1 and y-intercept -4.
    • We graph this only for values where x>2x > 2.

There are no values defined for 5x2-5 \leq x \leq 2, so we leave that part of the graph blank.

Would you like me to provide more details on how these lines were obtained or visualize this graph?
