Chapter 9: Q69. (page 534)

FIND THE ERROR Chase and Jade are finding the axis of symmetry of a parabola. Is either of them, correct? Explain your reasoning.

Short Answer

Expert verified

Yes, Jade is correct.

Step by step solution

01

Step 1. Standard form of quadratic function.

Compare the quadratic functiony=鈭�x2鈭�4x+6 with standard form of quadratic function, y=ax2+bx+c.

a=鈭�1b=鈭�4c=6

02

Step 2. Find the axis of symmetry.

The axis of symmetry is given by x=鈭�b2a. Substitute -1 for a, -4 for b into x=鈭�b2a.

x=鈭�鈭�42鈭�1=鈭�42=鈭�2

03

Step 3. Write the conclusion.

The obtained axis of symmetry matches with the axis of symmetry calculated by Jade. Chase forgot the negative sign with 4.

Therefore, Jade is correct.
