Full solution

Q. Which of the following graphs in the xy x y -plane have 3-3 and 55 as all of their distinct zeros for 6x6 -6 \leq x \leq 6 ?
  1. Problem Understanding: Understand the problem.\newlineWe need to find the graphs that have 3-3 and 55 as their only zeros within the interval 6x6-6 \leq x \leq 6. This means that the graph should touch or cross the x-axis at x=3x = -3 and x=5x = 5, and not at any other point within the given interval.
  2. General Form of the Polynomial: Determine the general form of the polynomial.\newlineA polynomial that has 3-3 and 55 as zeros can be written as f(x)=a(x+3)(x5)f(x) = a(x + 3)(x - 5), where aa is a non-zero constant. The value of aa will affect the width and direction of the graph but not the zeros.
  3. Additional Requirements: Check for additional requirements.\newlineSince the problem only specifies that 3-3 and 55 are the distinct zeros and does not mention any other conditions, any graph of the form f(x)=a(x+3)(x5)f(x) = a(x + 3)(x - 5) with a0a \neq 0 will satisfy the condition as long as it does not cross the x-axis at any other point within the interval 6x6-6 \leq x \leq 6.
  4. Behavior at the Zeros: Determine the behavior of the graph at the zeros.\newlineAt x=3x = -3, the graph should either touch or cross the x-axis, and the same goes for x=5x = 5. If a > 0, the graph will open upwards, and if a < 0, the graph will open downwards.
  5. Behavior Outside the Zeros: Verify the behavior of the graph outside the zeros. For x < -3, the graph should be above the x-axis if a > 0 and below the x-axis if a < 0. For -3 < x < 5, the graph should be below the x-axis if a > 0 and above the x-axis if a < 0. For x > 5, the graph should be above the x-axis if a > 0 and below the x-axis if a < 0.
  6. Graph Characteristics: Conclude the characteristics of the graph.\newlineThe graph of f(x)=a(x+3)(x5)f(x) = a(x + 3)(x - 5) will have 3-3 and 55 as its zeros, and it will not have any other zeros within the interval 6x6-6 \leq x \leq 6. The graph will either open upwards or downwards depending on the sign of aa, but this does not affect the location of the zeros.
