it's Claire's, the one you right here. So we're given up of X is equal to x cubed plus one turns e to the X We're gonna differentiate by applying the product rule and we get X cubed plus one d over t x Eat the X plus b to the x d over d x X cute plus one and we're gonna apply to some rule And when we simplify, we get e to the X times X cubed plus three X square close one. Now we're gonna determine second derivative So we're just gonna take the derivative of the 1st 1 We're just gonna ply the product and some rule once again and we get X cubed plus three x square plus one D over d x her e to the X plus e to the x d over d X execute plus three X square plus one. This becomes equal to X cubed less three x square plus one comes Eat the x close Eat the x three X square plus six sex because is equal to X cubed plus six x square plus six x plus one tongues heat, fax
