<p>What does b less than or equal to f(a) mean? I’m looking at #18 on page 400 in the blue book.</p>
<p>That means “b” the y-value is less than or equal to the y-value of the x-value “a” when plugged into the function f(a)…lol that sounds confusing doesn’t it?</p>
<p>kind of confused, but thanks for the reply.</p>
<p>I hate confusing questions that are too lame and easy ,but sometimes you cant understand what is asked in the problem.</p>
<p>I agree :). Can anyone else give me some insight?</p>
<p>lets say the equation was
f(x)=2x+5
lets say x is 5, f(5) would be 15.</p>
<p>b less than or equal to f(x) means that B has to be less than or equal to 15.
so technically, it has to be under the graph.</p>
<p>thanks guys</p>
