Can someone solve for this problem ? Thank you so much !!!

1. Define h(2) so that$\displaystyle h(x)=( X^2 + 3X - 10 )/( X-2 )$ IS CONTINUOUS AT X =1

2. wHAT VALUE SHOULD BE ASSIGNED to b to make the function

g (x) = { x^3 , x < 1/2

{ bx^2 ,x > and equal 1/2

3. Explain why the limits exist and give their values . Support with graphing utility !!

$\displaystyle lim [ ( 1 + cos X ) / 2 ]$

X--> 0

Thank you !!!
