Use the function f(x)=x^2-8 find the inverse of f(x)
likoan [24]

Answer:


Step-by-step explanation:

let : y = x² - 8

calculate : x

x² = y + 8

x exist : y + 8 ≥ 0

x = √(y + 8)    or x =  - √(y + 8)

conclusion :

if : x ≥ 0    the inverse of f(x) is : g(x) = √(x + 8)

if : x ≤ 0    the inverse of f(x) is : h(x) =  - √(x + 8)

10^x • 100^2x = 1000^5. Step by Step
nordsb [41]
Step one: set the base of each term to be the same (10)
(10ˣ)(10²)²ˣ = (10³)⁵
(10ˣ) (10⁴ˣ)= (10¹⁵)
10⁵ˣ = 10¹⁵
Because the indices are the same we can equate the two.
5x = 15
x = 3

Check 10⁵ˣ³ = 10¹⁵    10¹⁵=10¹⁵
