$$f(x)=3x^2-5x+5$$

$$f'(x)=(3x^2)’- (5x)’ + 5′ = 6x-5$$

$$f(x)=5x^2+6x-7$$

$$f'(x)=(5x^2)’ + (6x)’ — 7′ = 10x+6$$

$$f(x)=x^4+2x^2$$

$$f'(x)=(x^4)’ + (2x^2)’ = 4x^3+4x$$

$$f(x)=x^5-3x^2$$

$$f'(x)=(x^5)’ — (3x^2)’ = 5x^4-6x$$

$$f(x)=x^3+5x$$

$$f'(x)=(x^3)’ + (5x)’ = 3x^2+5$$

$$f(x)=-2x^3+18x$$

$$f'(x)=(-2x^3)’ + (18x)’ = -6x^2+18$$

$$f(x)=2x^3-3x^2+6x+1$$

$$f'(x)=(2x^3)’ — (3x^2)’ + (6x)’ + 1′ = 6x^2-6x+6$$

$$f(x)=-3x^3+2x^2-x-5$$

$$f'(x)=(-3x^3)’ + (2x^2)’ — x’ — 5′ = -9x^2+4x-1$$
