Question

1) find f'(x)
f'(x)=2x(cosx)-sinx(x^2+3)
2) sub in the x value (x=0 in this case)......this will give you value M
f'(0)=0
3) find y1 value by plugging x=0 back into original equation
f(0)=3
3) apply slope formula y-y1=m(x-x1)
y-3=0(x-0)
y=3

I am correct or not @satellite73 @lgbasallote

Answer 1

how would we know...there's no question o.O
