Given that lim x → 2 f ( x ) = 1 lim x → 2 g ( x ) = − 4 lim x → 2 h ( x ) = 0 limx→2f(x)=1 limx→2g(x)=-4 limx→2h(x)=0, find the

limits, if they exist. (If an answer does not exist, enter DNE.) (a) lim x → 2 [ f ( x ) + 5 g ( x ) ] limx→2[f(x)+5g(x)] (b) lim x → 2 [ g ( x ) ] 3 limx→2[g(x)]3 (c) lim x → 2 √ f ( x ) limx→2f(x) (d) lim x → 2 4 f ( x ) g ( x ) limx→24f(x)g(x) (e) lim x → 2 g ( x ) h ( x ) limx→2g(x)h(x) (f) lim x → 2 g ( x ) h ( x ) f ( x ) limx→2g(x)h(x)f(x)

Answer:

According what I can read, I have the following statements:

\lim_{x \to 2} f(x) = 1

\lim_{x \to 2} g(x) = -4

\lim_{x \to 2} h(x) = 0

a) Applying properties of limits

\lim_{x \to 2} f(x) + 5g(x) =  \lim_{x \to 2} f(x) + 5  \lim_{x \to 2} g(x) = 1 + 5*-4 = -19

b) Applying properties of limits

\lim_{x \to 2} g(x)^{3} = {(\lim_{x \to 2} g(x))}^{3} = (-4)^{3} = -64

c) Applying properties of limits

\lim_{x \to 2} \sqrt{f(x)} = \sqrt{\lim_{x \to 2} f(x)} = \sqrt{1} = 1

d) Applying properties of limits

\lim_{x \to 2} 4*g(x)*f(x) = 4*\lim_{x \to 2} g(x)*\lim_{x \to 2} f(x) = 4*-4*1 =-16

e) Applying properties of limits

\lim_{x \to 2} g(x)*h(x) = \lim_{x \to 2} g(x)*\lim_{x \to 2} h(x) = -4*0 =0

f) Applying properties of limits

\lim_{x \to 2} g(x)*h(x)*f(x) = \lim_{x \to 2} g(x)*\lim_{x \to 2} h(x)*\lim_{x \to 2} f(x = -4*0*1 =0

Evaluate 5k + 1 when: *
wlad13 [49]

1

k^2 = 4k

k = 0, k = 4

#2

k^2 - 5k = k + 7

k^2 - 6k = 7

k^2 - 6k + 9 = 16

k - 3 = 4 ⇒ k = 7

k - 3 = -4 ⇒ k = -1

#3

k^3 - 5k^2 + 3k = -k

k^3 - 5k^2 + 4k = 0

k(k^2 - 5k + 4) = 0

k = 0, k = 1, k = 4

#4

|k + 1| + 2 = 8

|k + 1| = 6

k = 5, k = -7

Iliada went to Minewaska state park one day this summer. All of the people at the park were either either hiking or bike riding.
Dennis_Churaev [7]
B r = 178 + h;
b r + h = 676;
then, 178 + 2h = 676 => h = 498/2 = 249 => b r = 178 + 249 = 427;
