Find the range of the function for the values given. A merchant uses the rule f (c) = (2 × c) + 1 to set his selling price.


c 1 2 3
f(c)

f(c) = (2 * c) + 1

when c = 1
f(1) = (2 * 1) + 1
f(1) = 3 <== range

when c = 2
f(2) = (2 * 2) + 1
f(2) = 5 <== range

when c = 3
f(3) = (2 * 3) + 1
f(3) = 7 <== range

range (all the f(c)'s) = {3,5,7}

Answer:

Range of function is {3,5,7}

Step-by-step explanation:

We have been given an expression:

f(c)=(2 x c)+1

We will substitute given values of c in f(c) to find f(c)

when c=1

f(c)=(2 x 1)+1=3

when c=2

f(c)=(2 x 2)+1=5

when c=3

f(c)=(2 x 3)+1=7

Hence, Range is the values f(c) will take

So, the values of f(c) are 3,5,7

Hence, range of function is {3,5,7}
