Question

Given f(x) = 2x + 1, find the range value if the domain value is 1.75.

Answer 1

Given:

The function is

$f(x)=2x+1$

To find:

The range value if the domain value is 1.75.

Solution:

Domain is the set of input values and range is the set of output values.

Here, range value if the domain value is 1.75. It means the value of function f(x) at x=1.75.

Substitute x=1.75 in the given function.

$f(1.75)=2(1.75)+1$

$f(1.75)=3.5+1$

$f(1.75)=4.5$

Therefore, the required range value is 4.5.
