<span>1) f(x) = x^2 + 2x
So lets replace all the x parts with (a-3)
f(a-3) = (a-3)^2 + 2(a-3)
and the rest is just expanding it out from there. </span>A: a^2-4a+3<span>
</span>2. If f(x0=x/x-3 and g(x)=2x-1, find (f-g)(x) A: -2x^2+8x-3/x-3
3. If f(x)=x^2+1 and g(x)=1/x, find [f*g](x) A:1/x^2 +1
4. Which equation best represents a line perpendicular to the graph of x+3y=9? A:y=3x-1
5. Which of the following describes the graphs of 2x+5y=9 and 10x=4y+18? A: perpendicular
6. Write the standard form of an equation of the line parallel to the graph of x-2y-6=0 and passing through A(-3,2) A: x-2y+7=0
