Write the inverse function for the function, ƒ(x) =x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.

inverse of f(x)= x+4 is

f-1(4)= 0

Step-by-step explanation:

replace f-1(x) by y:

then, rearrange the equation to make x the subject.

now change the y to x, and the x at the beginning to f-1(x). you get:

which is the answer.

for the second part, simply replace the x in equation that we got above to get:

so, f-1(4) = 0

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
