If [tex]f(x) = 4x + 5[/tex], find [tex]f(5)[/tex].

F(5)=4x+5 F(5) is 0 at this point Subtract 5 from both sides -5=4x Divide both sides by 4 -5/4=x So f(5)=-5/4

The value of the function f(x) = 4x +5 at x = 5 is** f(5) = 25**
What is function?
"It is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output."
For given example,
Given function : f(x) = 4x +5
We need to find the value of f(x)
This means, we need to find the function f(x) when x = 5
Substitute x = 5 in the given function .
⇒ f(x) = 4x +5
⇒ f(5) = 4(5) +5
⇒ f(5) = 20 + 5
⇒ f(5) = 25
Therefore,** f(5) = 25**

To evaluate the function f ( x ) = 4 x + 5 at x = 5 , substitute 5 into the function. This gives f ( 5 ) = 4 ( 5 ) + 5 = 25 , so f ( 5 ) = 25 .
