Answer:
g(x) = 2x – 3 is the function has an inverse that is also a function.
The correct option is A.
Inverse function;
The inverse of a function is the equation where x and y have switched places.
Here g(x) = 2x - 3 has inverse x = 2y - 3 which simplifies to;
k(x) = - has the inverse x = which simplifies to;
f(x) = |x+2| is an absolute value function.
w(x) = -20 does not have an inverse which is a function.
Therefore
The function has an inverse that is also a function is g(x) = 2x – 3.

Answer:
49
Step-by-step explanation:
Since x equals 4 you have to do 6×4 which is 24 then add 25 and it gives you 49
The answer is 17.5.
To do this, first I’d work out 10% of 50. To do this, divide 50 by 10. (Because you’re getting from 100% to 10%, and to do that you divide by 10, meaning you need to do the same for the 50)
This gives 5. You need 3 of those to get 30, so multiply 5 by 3.
This gives 30% = 15
Then the remaining 5% can be found by halving the 10% we had, which was 5. Half of 5 is 2.5.
Then you add 30% and 5% to get 35%, giving 15 + 2.5, which equals 17.5.
The common difference in this sequence is 6
The sum of n terms of an arithmetic sequence is given by:
S = n/2 [2a₁ + (n - 1)d]
S = 22/2 [2(8) + (22 - 1)(6)]
S = 1562
The answer is C
Heyy how are youhope your doing good!
