Question

a)

The interval notation (-3, 1) described in set builder notation is {* | -3 5xs1} {x-3<x<1) {x-35x<1} {x|-3<x51}

b)

The set-builder notation {xl-55x<8} is equivalent to (-5,8) O(-5, 8] O [-5,8) O [-5, 8]

c)

To solve 2x - 11<3, one must consider only one case two different cases three different cases O four different cases

d)

If f(x) = 3x2 and g(x) = x + 2, then (gf)(x) is 3x2 + 2 3x3 + 6x2 03x2 + x + 2 3x2 + 12x + 12
