Question

The polynomial functions f(x) = -13x and g(x) = -13 + x are equal.

Answer 1

TRUE OR FALSE?

Answer 2

Well the easiest way to figure this out is to check and some inputs. If x is 1, are the two equal?

Answer 3

yes

Answer 4

Are they? For x = 1, you have:

f(1) = -13 * 1
g(1) = -13 + 1

Answer 5

What is -13 * 1?

Answer 6

-13

Answer 7

And what is -13 + 1?

Answer 8

-12

Answer 9

Right. So \(f(1) \ne g(1)\), which means f(x) can't equal g(x).

Answer 10

so its false.

Answer 11

(For f(x) to be equal to g(x), the two must give the same results for all values of x.)

Answer 12

Exactly.
