What’s the derivative of x^2 - 3

geniusboy [140]

Answer:

$\displaystyle \frac{dy}{dx} = 2x$

General Formulas and Concepts:

Calculus

Differentiation

Derivatives
Derivative Notation

Derivative Property [Multiplied Constant]: $\displaystyle \frac{d}{dx} [cf(x)] = c \cdot f'(x)$

Derivative Property [Addition/Subtraction]: $\displaystyle \frac{d}{dx}[f(x) + g(x)] = \frac{d}{dx}[f(x)] + \frac{d}{dx}[g(x)]$

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle y = x^2 - 3$

Step 2: Differentiate

Derivative Property [Addition/Subtraction]: $\displaystyle y' = \frac{d}{dx}[x^2] - \frac{d}{dx}[3]$
Basic Power Rule: $\displaystyle y' = 2x$

Answer:

a) k(x) = 5x - 2

x = 5(y) - 2

5y = x + 2

y = (x+2)/5

k-¹(x) = (x+2)/5

b) h(x) = (x+10)/(x-3) 

x = (y+10)/(y-3)

x(y-3) = y + 10

xy -3x = y + 10

xy - y = 3x + 10

y(x-1) = 3x + 10

y = (3x + 10)/(x-1)

h-¹(x) = (3x+10)/(x-1)
