Answer 2

`\huge \boxed{\mathfrak{Question} \downarrow}`

• What is the answer to
  `\sf \: f ( x ) = - 3 x ^ { 2 } - 20`

`\huge \boxed{\mathfrak{Answer} \downarrow}`

`\large \boxed{ \bf \: - 6x}`

`\huge \boxed{\mathfrak{Explanation} \downarrow}`

`\large \sf \: f ( x ) = - 3 x ^ { 2 } - 20`

• The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of
  `\sf \: ax^(n)` is
  `\sf \: nax^(n-1)`.

`\large \sf \: 2* ( -3x)^(2-1)`

• Multiply 2 times - 3.

`\large \sf \: - 6x^(2-1)`

• Subtract 1 from 2.

`\large \sf \: - 6x^(1)`

• For any term t, t¹ = t.

`\large \boxed{ \bf \: - 6x}`
