Question 8 • Algebra II
Which graph can be used to find the solution(s) to x squared minus 1 is equal to x plus 1 ?
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 origin and (1 comma 1). 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 5 to 5 with an interval of 1 unit. A line passes through (0 comma 1) and (negative 1 comma 0). 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).
C
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 (0 comma 1) and (negative 1 comma 0). A parabola opens down, has vertex at (0 comma 1) and cuts the x axis at (negative 1 comma 0) and (1 comma 0).
D
