Bonjour j’ai besoins d’aide pour cet exercice 13 merci d’avance

bonsoir

f (x) = 5 x² - 3 x + 1

f' (x) = 10 x - 3

f ' (1) = 10 - 3  = 7

f ' ( 2) = 20 - 3 = 17

f ' (0) = - 3

Bonsoir

f(x) = 5x^2- 3x +1

f(-1) = 5 * (-1) ^2 - 3 *(- 1) +1

f(-1) = 5 * 1 - 3 + 1

f(-1) = 5 - 3 + 1

f(-1) = 2 + 1

f(-1) = 3

f(2) = 5 * 2 ^2 - 3 * 2 + 1

f(2) = 5 * 4 - 3 *2 + 1

f(2) = 20 - 6 + 1

f(2) = 14 + 1

f(2) = 15

f(0) = 5 * 0^2 - 3 * 0 + 1

f(0) = 5 * 0 - 3 * 0 + 1

f(0) = 0 - 0 + 1

f(0) = 1
