Will award brainiest to detailed answer! Linear Approximation
Let f be a function with f(0) = 1 and f'(x) = cos (x^2).
a) Find the linearization of f at x = 0.
b) Estimate the value of f at x = 0.1.
c) Do you think the actual value of f at x = 0.1 greater than or less than the estimate in part (b)? Explain.

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
