Question

100 points consider the function below -2|x-3|+1 = -2sqrtx-1

Answer 1

D. x = 1.7 or x = 5.7

Explanation:

The left side of the equation is graphed in blue. The right side of the equation is graphed in red.

The solution of the equation is the x (and y) that make both equations true.

On the graph these solutions are the points where the two graphs intersect.

Those two points have x values that are positive (and y's that are negative) Only answer D. has x-values that correspond to the x-values of the points of intersection.

Answer 2

• D. x ≈ 1.7 or x ≈ 5.7

Explanation:

The solution is the x-coordinate of the intersection of the graphs (blue line and red curve).

The points are:

• x close to 2 and close to 6

Correct choice is D
