Question

Find the derivative equation of:
y=−2.5x^2+0.5x−1.42

I thought 5x+(1/2) was the answer but it is not

Answer 3

hint:
we have these subsequent derivatives:
\[\Large \begin{gathered}
{x^2} \to 2x \hfill \\
\hfill \\
x \to 1 \hfill \\
\end{gathered} \]

Answer 4

subsequent?

Answer 5

yes! I wrote the derivatives of the functions \(x^2\) and \(x\) respectively

Answer 6

hint:
the derivative of the first term is \(-2.5 \cdot 2 \cdot x\)

Answer 7

oh

Answer 8

so its just -5x+1/2
