Find the differential of the function f(x)= sqrt{x^2+5x} . Select one: The differential of a function f is given by: Select one: a. dx=f'(x)dy b. dx/dy =f'(x) c. dydx=f'(x) d. dy=f'(x)dx e. dy=f'(x) The Linearization of a function f(x)=x^2 at a=4 is given by: Select one: a. L(x)=16+8(x-4) b. L(x)=8x-4 c. L(x)=8+(x-4) d. L(x)=16+(x-4) e. L(x)=8+16(x-4) In order to find the Linearization of the function f(x)= sqrt{x-5} at a number a , we first find f'(a) : Select one: a. f'(a)= 1/sqrt{a-5} b. f'(a)=1/2 sqrt{a-5} c. f'(a)= 2/sqrt{a-5} d. f'(a)= sqrt{a-5} e. f'(a)=2 sqrt{a-5} 5.The Linearization of a function f at a number a is given by: Select one: a. L(x)=f'(a)+f(a)(x-a) b. L(x)=f'(a)-f(a)(x-a) c. L(x)=f(a)-f'(a)(x-a) d. L(x)=f(a)-f'(a)(x+a) e. L(x)=f(a)+f'(a)(x-a)
