An function is graphed on the coordinate plane.An function is graphed on the coordinate plane. From left to right, the function starts at infinity and comes to a cusp at left parenthesis negative 1 comma 0 right parenthesis, then reaches a local maximum at left parenthesis 0 comma 1 right parenthesis, reaches another cusp at left parenthesis 1 comma 0 right parenthesis, and then continues to infinity.

Based on the description of the graph:

  • The function has cusps at \((-1, 0)\) and \((1, 0)\), which suggests that these points are where the function changes direction but does not cross the x-axis.
  • The function reaches a local maximum at \((0, 1)\), which is also the y-intercept (since \(x = 0\)).
  • There are no mentions of the function crossing the x-axis at any point other than the cusps.

From this information, the x-intercepts and y-intercepts can be identified as follows:

  • X-intercepts: The function touches the x-axis at \((-1, 0)\) and \((1, 0)\) but does not cross it, hence these are not true x-intercepts in the traditional sense. Given the options:

    • The x-intercepts are when the function equals zero, which happens at \((-1, 0)\) and \((1, 0)\).
  • Y-intercept: Since the function reaches a value of 1 at \(x = 0\), the y-intercept is \((0, 1)\).

So, the correct identification is:

  • X-intercepts: \((-1, 0)\) and \((1, 0)\)
  • Y-intercept: \((0, 1)\)

Thus, the correct response from your options is: x-intercepts: left-parenthesis negative 1 comma 0 right-parenthesis; and left-parenthesis 1 comma 0 right-parenthesis y-intercept: left-parenthesis 0 comma 1 right-parenthesis.
