I am also on the next question, i have solved a few and struggling with others?
2. obtain dy/dx for the following functions using the 'direct rule'
a) y=2.5x^2
=5x
b) y=x^2/2.5
=0.8x
c) y=2.5x - 2.5
=-2.5x^0
d)y= (2.5)(SQUAREROOT OF x)
=1.25x
e)y=x^2.5
=2.5^1.5
f)y=2.5/x^2 HELP
g)y=(^2.5 SQUARE ROOT OF x) HELP
h)y=2.5x^4 - (x^3/2.5) - (x/2.5) + 2.5 SO FAR
=10x^3 - 1.2x^2 - 0.4x^0 + 2.5
I)y=2.5x{(x^2)-(1)} HELP
J) y=(x^3 - 2.5x^2) / (2.5) (SQUARE ROOT OF x) HELP
