Question

find the first and second derivative of the function.

f(x)=-7x^2e^x

Answer 1

the first derivative:
14e^x(1+x)
the second derivative:
e^x(28+14x)

let me know if you want me show you how to get them

Answer 2

y = -(7x^2)(e^x)
y' = -(14xe^x + 7x^2e^x)

y'' = -(14e^x + 14xe^x

I might have gotten confused with (-)
