If (x) = 7 -x , find f(3)
2 answers:
Hey there!!
Given :
f( x ) = 7 - x
What is f(x)?
f(x) is basically the y.
The question states :
y = 7 - x
Now, find ( 3 )
This states that, I have given the value for x and find y.
y = 7 - x
y = 7 - 3
y = 4
Hence, f(3) = 4
Hope helps!
f(3) means you replace x with 3.
f(x) = 7-x
f(3) = 7-3
f(3) = 4
