You can put this solution on YOUR website!
+f%28x%29+ says " the right side of this equation
depends only on the value of x"
------------------
And, if you look at the right side, it depends
only on the value that you choose for x
------------------
+f%283%29+ tells you to choose +x+=+3+
for the right side, so
+f%283%29+=+3%2A3+-+7+
+f%283%29+=+9+-+7+
+f%283%29+=+2+
