Question 9 • Algebra II
Which graph can be used to find the solution(s) to x squared minus 1 is equal to 3 ?
Answer
A
Image with description On a coordinate plane, the scale on the x and y axes ranges from negative 5 to 5 with an interval of 1 unit. A line passes through the (negative 3 comma 0) and (0 comma 3). A parabola opens up, has vertex at (0 comma negative 1) and cuts the x axis at (negative 1 comma 0) and (1 comma 0).
B
Image with description On a coordinate plane, the scale on the x and y axes ranges from negative 9 to 9 with an interval of 1 unit. A line is parallel to the x axis and cuts the y axis at (0 comma 3). A parabola opens up, has vertex (0 comma negative 1) and cuts the x axis at (negative 1 comma 0) and (1 comma 0).
C
Image with description On a coordinate plane, the scale on the x and y axes ranges from negative 9 to 9 with an interval of 1 unit. A line is parallel to the y axis and cuts the x axis at (3 comma 0). A parabola opens up, has vertex (0 comma negative 1) and cuts the x axis at (negative 1 comma 0) and (1 comma 0).
D
Image with description On a coordinate plane, the scale on the x and y axes ranges from negative 9 to 9 with an interval of 1 unit. A line passes through the origin and (1 comma 3). A parabola opens up, has a vertex (0 comma negative 1) and cuts the x axis at (negative 1 comma 0) and (1 comma 0).
