I need help with these 3 calculus questions:

WeBWorK 3 - Topics 6 - 7: Problem 1 (1 point) Use linear approximation to approximate v 25.4 as follows. Let f(a:) = V5. The equation of the tangent line to f(.'c) at a: = 25 can be written in the form y = m1: + b. Compute m and b. m: b= I m I m Using this find the approximation for v 25.4. Answer: 1 Note: You can earn partial credit on this problem. WeBWork 3 - Topics 6 - 7: Problem 2 (1 point) Find the linearization of f(x) = $3x + 5 at the point x = 1.
