Consider f(x)=y.

Simplify the equation f(x)=y to obtain the value of x in terms of y.

So inverse of function is,

Correct nswer is A part.
1/3(n + 4) - 6 = -2 <== ur equation
1/3n + 4/3 - 6 = -2 ...multiply by 3
n + 4 - 18 = - 6
n - 14 = -6
n = -6 + 14
n = 8 <== ur number
Answer:
Step-by-step explanation:
First of all, your question is very clear. Excluding 0 is a needed restriction.
f(1) = 3*1 + 1 = 3 + 1 = 4
f(2) =3*2 + 1 = 6 + 1 = 7
f(3) = 3*3 + 1 = 9 + 1 = 10
f(4) = 4*3 + 1 = 12 + 1 = 13
4,7,10,13
Notice that you are just adding 3 to the previous term.
Answer:
D: 14 = 0.89 x n; 15.7
Step-by-step explanation:
To get 89% of a number you have to multiply that number by 0.89
