Step-by-step explanation:

multiplying expressions.

remember every term of one expression has to be multiplied with every term of the other expression, and the results are added up (while considering their individual signs, of course).

1.

(-3×3 + 2x - 4)(3x - 2)

(-9 + 2x - 4)(3x - 2)

(-13 + 2x)(3x - 2) = -13×3x + -13×-2 + 2x×3x + 2x×-2 =

= -39x + 26 + 6x² - 4x = 6x² - 43x + 26

2.

let's do the other multiplication and compare the result with the result of 1 :

(-13 + 2x)(2x - 3) = -13×2x + -13×-3 + 2x×2x + 2x×-3 =

= -26x + 39 + 4x² - 6x = 4x² - 32x + 39

no, this product is not the same as in 1.

Inverse of f(x) = x2 − 9
luda_lava [24]
To find the inverse of a function, replace every x in the equation with a y, and replace every y in the equation with an x:

x = y^{2} - 9

Add 9 to both sides:

y^{2} = x + 9

Square root both sides to get y by itself:

y = \sqrt{x+9}

This equation can be simplified by taking the square root of 9 out of the root:

\sqrt{9} = 3
y = 3 + \sqrt{x}

The inverse of this function is y = 3 + √x.
