1/       x0+deltax=x1=4.01   f(x0)=1+2*4=9
          f(x1)=1+2*4.01=1+8.02=9.02   delta f(x) =9.02-9=0.2

2/       f(x)=-5x+1.6  f(x0)=-5(-5)+1.6=25+1.6=26.6
          x1=-5-0.1=-5.1   f(-5.1)=-0.55(-5.1)+1.6=27.1
           delta f(x)=27.1-26.6=0.5

In Australia we have a party to celebrate our birthdays. Everyone brings a small gift. My mum
always makes me a birthday cake. We have a table full of food: crisps, sandwiches, small cakes
and chocolate biscuits, ice cream and very small sausages you eat on a stick.
I just love them. We decorate the house with balloons and I play party games with me friends.
It's fantastic!
