Answer:hello :
let : y = f(x)
you have : y = x² + 5
calculate : x
x² = y - 5
x exsit for : y - 5 ≥ 0
if : x ≥ 0 x = √( y - 5) so the inverse functio for f is : g(x) = √( x - 5)
if : x ≤ 0 x = - √( y - 5) so the inverse functio for f is :h(x) = - √( x - 5)
Answer:
x^2 - 2x - 8.
Step-by-step explanation:
Using long division:
x - 2)x^3 - 4x^2 - 4x + 16( x^2 - 2x - 8 <------ Quotient
x^3 - 2x^2
-2x^2 - 4x
-2x^2 + 4x
- 8x + 16
-8x + 16

Answer:
1/6
Step-by-step explanation:
Starting with 2 cubes that have 6 numbers total for each one, so 2 cubes will have 12 numbers total, and the probability of number 5 is 2/12 (because each cube has a number 5, so two cubes will have 2, and fraction for it will be 2/12). After simplification, the final result is 1/6.
Answer:
3/4 lb
Step-by-step explanation:
Lightest: 3 3/4
Heaviest: 4 1/2 = 4 2/4
4 2/4 - 3 3/4 = 18/4 - 15/4 = 3/4
Answer:
I assume that says 
, but that is the case because when we square a number, we can NEVER get a negative number. The smallest square we can get is 0. 1^2 is 1, and no real number squared gives us a negative number.
