Answer:

x² - 6x + 9

Step-by-step explanation:

(x - 3)²

= (x - 3)(x - 3)

Each term in the second factor is multiplied by each term in the first factor

= x(x - 3) - 3(x - 3) ← distribute both parenthesis

= x² - 3x - 3x + 9 ← collect like terms

= x² - 6x + 9 ← in standard form

Which statement must be true? a b c d

lozanna [386]

ANSWER

$\boxed {m \ne0}$

EXPLANATION

The given function is

$f(x) = mx + b$

We need to find the inverse of this function,

Let

$y= mx + b$

We interchange x an y to obtain,

$x = my + b$

We solve for y now to obtain,

$x - b = my$

We divide through by m to get,

$\frac{x - b}{m} = y$

Hence the inverse function is ,

${f}^{ - 1} (x) = \frac{x - b}{m}$

For this inverse to exist, the denominator must not be equal to zero,

Thus

$m \ne0$

The correct answer is A.
