f(x)=2x-5

the red line is f(x)

green line is a rotation about (0,-5)

now we try to define the green line an then multiply by 3

for this we just change the slope sign to obtain the fuction


-2x-5

no multiply by 3


h(x)=-6x-15

Let f(x)=2x-5 . write a function h whose graph is a rotation of f (x) about (0,-5) by-example-1
