Question
Let $f(x, y)=2 x+3 y-4 .$ Compute $f(0,0), f(1,0), f(0,1), f(1,2),$ and $f(2,-1)$
Step 1
$$ To compute $f(1,0),$ we substitute $x=1$ and $y=0$ into the expression for $f(x,y)$: $$f(1,0)=2(1)+3(0)-4=2+0-4=-2.$$ To compute $f(0,1),$ we substitute $x=0$ and $y=1$ into the expression for $f(x,y)$: Show more…
