Sometimes it helps to draw it...so u can see

7 7
J_______K_________L
|__________________|
4x - 2

since K is the midpoint, it splits the segment in 2 equal parts
JK + KL = JL
7 + 7 = 4x - 2
14 = 4x - 2
14 + 2 = 4x
16 = 4x
16/4 = x
4 = x <====

KL = 7 <===
JL = 4x - 2....4(4) - 2.....16 - 2 = 14 <==

Answer:

f(-9) = 279

Step-by-step explanation:

f(x) = 4x^2 + 7x + 18

f(-9) = 4(-9)^2 +7(-9) + 18

= 4(81) - 63 + 18

= 324 - 63 + 18

= 279

Answer:

The answer is

$f(x) = {\displaystyle 8 + \frac{-28}{1}(x+2)+\frac{-36}{2!}(x+2)^2 + \frac{-18}{3!}(x+2)^2 }$

Step-by-step explanation:

Remember that Taylor says that

$f(x) = {\displaystyle \sum\limits_{k=0}^{\infty} \frac{f^{(k)}(a) }{k!}(x-a)^k }$

For this case

$f^{(0)} (-2) = 8(-2)-3(-2)^3 = 8\\f^{(1)} (-2) = 8-3(3)(-2)^2 = -28\\f^{(2)} (-2) = -3(3)2(-2) = -36\\f^{(2)} (-2) = -3(3)2 = -18$

$f(x) = {\displaystyle 8 + \frac{-28}{1}(x+2)+\frac{-36}{2!}(x+2)^2 + \frac{-18}{3!}(x+2)^2 }$
