Question
Tell whether (11, 11) is on the graph of f(x) = IxI. If it is, give the coordinates of another point with the same y value.
Yes, (-11, 11)
No
Yes,
Yes,
Hint:
We simply plug in the values of x given in the coordinates to check the status of the said point. Then, we put the same value of x with the opposite sign and find the corresponding value of y.
The correct answer is: Yes, (-11, 11)
Step 1 of 2: x = 11, f(x) = I11I = 11 So, yes, (11, 11) is on the graph. Step 2 of 2: Now, for x = -11, f(x) = I(-11)I = 11 So, (-11, 11) is on the graph. Final Answer: The right choice is-- B. Yes, (-11, 11)
