  • Yes; it passes the horizontal line test.
  • No; it is not a straight line.
  • Yes; it passes the vertical line test.
  • No; there is a line connecting the dots.
Is the relation a function? Why.
mt-6 sb-3-Functions and Function Notationimg_no 150.jpg
  • Yes, because the x-value 11 has two y-values pair with it.
  • Yes, because each x-value has only one y-value paired with it.
  • No, because the x-value 11 has two y-values pair with it.
  • No, because each x-value has only one y-value paired with it.

If f(x) = 2x+1, what would the function look like once you substitute in a 1 to find f(1)?
  • f(x) = 21+1
  • f(1) = 2 (1) + 1
  • f(1) = 2x (1) + 1
If f(x) = -3x - 8, find f(-1).
  • f(-1) = 5
  • f(-1) = -5
  • f(-1) = -12
  • f(-1) = -10
If f(x) = x2-x+3, what would the function look like once you substitute in a -3 to find f(-3)?
  • f(-3) = -32-3+3
  • f(-3) = (-3)2 -(-3)+3
  • f(-3) = (-3)2 -3+3
