1.) $$f(0)=3(0)^{2}-0+2$$
$$f(0)=0^{2}-0+2$$
$$f(0)=0-0+2$$
$$f(0)=2$$




$$f(1.5)=3(1.5)^{2}-1.5+2$$
$$f(1.5)=4.5^{2}-1.5+2$$
$$f(1.5)=20.25-1.5+2$$
$$f(1.5)=20.75$$




$$f(-4)=3(-4)^{2}-(-4)+2$$
$$f(-4)=-12^{2}+4+2$$
$$f(-4)=144+6$$
$$f(-4)=150$$

2.)
$$f(3)=-5(3)+9$$
$$f(3)=-15+9$$
$$f(3)=-6$$
$$Answer: -6$$
