Question

Can somebody help me with this calculus problem? If you could that would be much appreciated! Thank you. (100 points)

Answer 1

#a

-2<0

`\\ \sf\longmapsto f(x)=x^2`

`\\ \sf\longmapsto f(-2)`

`\\ \sf\longmapsto (-2)^2`

`\\ \sf\longmapsto 4`

#b

0=0

`\\ \sf\longmapsto f(x)=2`

`\\ \sf\longmapsto f(0)=2`

#c

2>0

`\\ \sf\longmapsto f(x)=2x+1`

`\\ \sf\longmapsto f(2)`

`\\ \sf\longmapsto 2(2)+1`

`\\ \sf\longmapsto 4+1`

`\\ \sf\longmapsto 5`
