Answer:

Step-by-step explanation:

The vertex form of a quadratic equation:

$y=a(x-h)^2+k$

(h, k) - vertex

$y=x^2+2x+18$

$y=x^2+2(x)(1)+1^2-1^2+18$ use (a + b)² = a² + 2ab + b² (*)

$y=\underbrace{x^2+2(x)(1)+1^2}_{(*)}-1+18$

$y=(x+1)^2+17\\\\y=(x-(-1))^2+17$

h = -1, k = 17

In the function f (x) = = (x²-1) / (x-1), what happens if x takes the value of 1? Explain your answer.

zhenek [66]

Answer:

If x=1, then f(x)= undefined

Step-by-step explanation:

1*1=1

1-1=0

0/0

You can't divide by 0, so anything that is divided by 0 is undefined.

((1*1)-1)/(1-1)

(1-1)/(1-1)

0/0

0/0=Undefined

f(x)= undefined
