1
The demand curve for a certain product is given by p=24-x. Find the marginal revenue!
R'(x)=22
R'(x)=-1
R'(x)=24x-x2
R'(x)=24-2x
2
Find the derivative of f(x)=5x^4+3x^2-2x-7
f'(x)=20x^3+6x-9
f'(x)=20x^3+6x-2
f'(x)=24
f'(x)=5+4x^3+3+2x-2-7
3
Find the derivative of y=(1/x)+√x
dy/dx = -x-2 + (1/2)x-1/2
dy/dx=1 + √x
dy/dx=-x0+1/(2√x)
dy/dx=x-1+x1/2
4
Find the derivative of g(x)=(2x+5)²
g'(x)=8x+20
g'(x)=4
g'(x)=49
g'(x)=2x+5
5
Find the derivative of y=(2x²-3)/(5x+4)
y'=[(4x)(5x+4)-5(2x2-3)]/(5x+4)2
y'=4x/5
y'=(-10x2-16x-15)/(5x+4)2
y'=(-10x2-16x-15)/(2x2-3)2
