Which row of the input/output table is incorrect?

zaharov [31]

Row A: x = 3

y = 2x - 3

y = 2(3) - 3 = 3 This is correct

Row B: x = 5

y = 2x - 3

y = 2(5) - 3 = 7 This is correct

Row C: x = 7

y = 2x - 3

y = 2(7) - 3 = 11 this is correct

Row D: x = 10

y = 2x - 3

y = 2(10) - 3 = 17 THIS IS INCORRECT, SO ROW D

F(x) = x2+3x+2 x2+5x+4 Why is there no zero at x = –1?

dmitriy555 [2]

You could rewrite $F(x)$ as

$\dfrac{x^2+3x+2}{x^2+5x+4}=\dfrac{(x+1)(x+2)}{(x+1)(x+4)}$

and be tempted to cancel out the factors of $x+1$ . But this cancellation is only valid when $x\neq-1$ .

When $x=-1$ , you end up with the indeterminate form $\dfrac00$ , which is why $-1$ is not a zero.
