Answer:
[tex]f(3)=8[/tex]
Step-by-step explanation:
Given: The function [tex]f(x)=5x-7[/tex]
To find: The value of the given function at x=3
Solution:
The given function is:
[tex]f(x)=5x-7[/tex]
Now, substituting the value of x in the above given function, we get
[tex]f(3)=5(3)-7[/tex]
Upon solving the above equation, we get
[tex]f(3)=15-7[/tex]
[tex]f(3)=8[/tex]
Therefore, the value of the given function at x=3 is 8.
