For f(x) = -5x +9, find f'(15)

Which polygon is she in the process of constructing ?

❤️ (geometry) does the construction demonstrate how to copy an angle correctly using technology a) yes; the distance between points a and f was used to create circle h b) yes; the distance between points f and g was used to create circle h c)no; the distance between points a and f was used to create circle h d) no; the distance between points f and g was used to create circle h

How many and of which kind of roots does the equation f(x)=x3−x2−x+1
