The inverse is y = x/2 - 4
Steps involved are -
- replace f(x) with y: y = 2(x + 4)
- Then switch y and x: x = 2(y + 4)
- Finally make y the subject:
- x = 2(y + 4)
- x/2 = y + 4 (divide by 2)
- x/2 - 4 = y (subtract 4)
- So, the inverse is y = x/2 - 4
<h3>What is the formula for inverse function?</h3>
- In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f.
- The inverse of f exists if and only if f is bijective.
- f-1(y) = y/2 = x, is the inverse of f(x).

Answer: x= 30 when y = 5
Step-by-step explanation:
So, first find the unit rate. 24/4 = 6
So, for ever y you have 6x.
5 * 6 = 30
Answer:
I think f(t)=1/4t
Step-by-step explanation:
Because of you multiply 1/8 times 2, it gives you 1/4. Not 100% sure tho
Answer:
x = 12 radical 2 ithink these is ansewer
By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is
<h3>What is
sequence ?</h3>
Sequence is collection of numbers with some pattern .
Given sequence

We can see that

and

Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2
Now
term of this Geometric progression can be written as

So summation of 15 terms can be written as
