1. Find the slope of the line tangent to the parabola: y = 4x - x ^ 2

At point (1,3):
a) Using the definition of the limit first and then using derivation rules
(derived from polynomials).
b) Find the equation of the tangent line at the point (1,3).
c) find the approximate value of “y” when x = 1.1; assuming you don't know
the parable, you only know the results of part a).

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
