Answer:
D. difference of squares
Step-by-step explanation:
Both of the terms x^2 and 9 are squares, so their difference is the difference of squares. The factorization of that is a "special form" that can be usefully memorized.
a^2 -b^2 = (a -b)(a +b)
x^2 -9 = (x -3)(x +3)
I had this question and SAS is the correct answer
Answer:
See, that doesn't make sense.
First of all, 4 is the only number equal to 4. Sp, it'd be 9+4 = 13
Then I'm assuming you're also subtracting 4 from 13, so the answer would be 9.
Hope this helped, have a nice day.
f(x)=4x
To find the inverse, first change f(x) to y:
y = 4x
Now switch the variables:
x = 4y
Solve for Y:
Divide both sides by 4:
y = x/4
Now replace y with the inverse function f^-1(x):
f^-1(x) = x/4
