1 For each function , calculate: i f(2) ii f(-2) iii f(0.5) iv f(0) a f(x)=3x+2 b f(x)=5x-2 f(x)=2x-1 d f(x)=2x^2+3 e f(x)=x^2-2x f(x)=x^3-2

Let's calculate the values for each function:

a) $$f(x)=3x+2$$
i) $$f(2)=3(2)+2=8$$
ii) $$f(-2)=3(-2)+2=-4$$
iii) $$f(0.5)=3(0.5)+2=3.5$$
iv) $$f(0)=3(0)+2=2$$

b) $$f(x)=5x-2$$
i) $$f(2)=5(2)-2=8$$
ii) $$f(-2)=5(-2)-2=-12$$
iii) $$f(0.5)=5(0.5)-2=0.5$$
iv) $$f(0)=5(0)-2=-2$$

c) $$f(x)=2x-1$$
i) $$f(2)=2(2)-1=3$$
ii) $$f(-2)=2(-2)-1=-5$$
iii) $$f(0.5)=2(0.5)-1=-0.5$$
iv) $$f(0)=2(0)-1=-1$$

d) $$f(x)=2x^{2}+3$$
i) $$f(2)=2(2)^{2}+3=11$$
ii) $$f(-2)=2(-2)^{2}+3=11$$
iii) $$f(0.5)=2(0.5)^{2}+3=3.5$$
iv) $$f(0)=2(0)^{2}+3=3$$

e) $$f(x)=x^{2}-2x$$
i) $$f(2)=(2)^{2}-2(2)=0$$
ii) $$f(-2)=(-2)^{2}-2(-2)=6$$
iii) $$f(0.5)=(0.5)^{2}-2(0.5)=-0.75$$
iv) $$f(0)=(0)^{2}-2(0)=0$$

f) $$f(x)=x^{3}-2$$
i) $$f(2)=(2)^{3}-2=6$$
ii) $$f(-2)=(-2)^{3}-2=-10$$
iii) $$f(0.5)=(0.5)^{3}-2=-1.875$$
iv) $$f(0)=(0)^{3}-2=-2$$
