Find f'(x) (the derivative of f(x)) if f(x) = 7x^3 - 2x^2 + 4x - 5.
The derivative of a polynomial equation can be found by multiplying the exponent of the variable by the coefficient of each term, then by reducing the exponent of the variable by one. Answer: 21x^2 - 4x + 4
Solve the equation 5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13
Detailed solutions to algebra problems are presented. Solution to Problem 1: Given the equation 5 (- 3 x - 2) - (x - 3) = - 4 (4 x + 5) + 13 Multiply factors. -15 x - 10 - x + 3 = - 16 x - 20 + 13 Group like terms. - 16 x - 7 = - 16 x - 7 Add 16x + 7 to both sides and write the equation as follows 0 = 0 The above statement is true for all values of x and therefore all real numbers are solutions to the given equation.
