Question

given the function f defined by the formula f (x)=2x + 1 find the following: evaluate f(4)f(4)=f(4)=f(4)=

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

f (x) = 2x + 1

f(4) = ?

Step 02:

x = 4

f (4) = 2*4 + 1

f (4) = 8 + 1

f (4) = 9

The answer is:

f (4) = 9
