Use the definition of the derivative to find f'(-2), where f(x) = x^3 - 2x

10

Step-by-step explanation:

10

Step-by-step explanation:

f'(x) = 3x² - 2

f'(-2) = 3(-2)² - 2

= 3(4) - 2

= 12 - 2 = 10

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
