Answer:
9
Step-by-step explanation:
replace x = 2 into f(x)=7x-5
f(2)=7(2)-5 = 14 -5 = 9
answer is 9
For this case, we have a function of the form [tex]y = f (x)[/tex], where [tex]f (x) = 7x-5[/tex]
You want to know the value of the given function when [tex]x = 2[/tex],
Then we substitute [tex]x = 2[/tex] in the function:
[tex]f (2) = 7 (2) -5\\f (2) = 14-5\\f (2) = 9[/tex]
So, the value of the function is 9 when [tex]x = 2[/tex]
Answer:
[tex]f (2) = 9[/tex]
