Question

A function f is defined as follows:
f(x) = 5 - x for 0 ≤ x ≤ 4
Find the value of x such that f(x) = 3 and f(x) = 5

Answer 1

hey...
it's.... clear.... x = 0 or 2
such that.....
f(0) = 5 - 0 = 5
or...
f (2) = 5 - 2 = 3
hope it will helpful ✌

Answer 2

Answer:

The value of x = 3 or value of x = 0

Step-by-step explanation:

In this question

We have been given that

Function is defined as

f(x) = 5 - x for 0 ≤ x ≤ 4

We need find the value of x such that f(x) = 3 and f(x) = 5

According to the question

If f(x) = 3

Then, f(x) = 5 - x for 0 ≤ x ≤ 4

Putting the value of x we get,

3 = 5 - x

x = 5 - 3

x = 2 and x is in between [0,4]

If f(x) = 5

f(x) = 5 - x  for 0 ≤ x ≤ 4

Putting the value of f(x) we get

5 = 5 - x

x = 5 - 5

x = 0 for x in between [0,4]

Hence, value of x = 0 for f(x) = 5

and       value of x = 2 for f(x) = 3
