A function is given algebraically by the formula f(x) = (x − 2)2 + 1

Question

A function is given algebraically by the formula f(x) = (x − 2)² + 1. Complete these other ways to represent f:

(a) Verbal: "Subtract 2, then  ---Select--- take the square root of the result add 1 square the result subtract 1 multiple by 2 and  ---Select--- subtract 1 multiple by 2 square the result add 1 take the square root of the result .

(b) Numerical:

xf(x)
0	5
2

6

Answer 1

The function tells you what's happening to x.

What happens after you subtract 2 from x, according to that equation?

The (x-2) quantity is squared.

Then there's +1.
