FUNCTIONS AND THEIR GRAPHS; find f(2), F(0) AND F(-2) for each function. (a) f(x)=3x-1 (b) f(x)=4-x^2 (c) f(x)=x^3+8 (d) f(x)=2^x please explain how to do these questions as well. :)

Find the equation of the chord of the parabola joining the points with parameters (a)1 and -3 on x=2t, y=t^2 (b)1/2 and 2 on x=4t, y=2t^2 (c)-1 and -2 on x=t, y=1/2t^2 (d)-2 and 4 on x=1/2t^2, y=1/4t^2 Then use the formula y=1/2(p+q)x-apq to obtain the ch...

how do you find the horizontal and vertical assymptotes of the curve y= x/ x+3 and also the intercepts. so that you can approximate the area under the curve from x=1 to x=5 using 5 function values? THANKYOU,
