Question

suppose f and g are functions for which the lim f(x)=25 as x goes to -2 and lim g(x) =10 use limit properties to find the following limits.
a. lim g(x)/f(x) as x goes to -2
b. lim square root f(x)g(x) as x goes to -2
c. lim 4f(x)+2/1-g(x)+f(x) as x goes to -2

Someone please help ! Thanks

Answer 1

suppose f and g are functions for which the lim f(x)=25 as x goes to -2 and lim g(x) =10 use limit properties to find the following limits

a.\[\lim_{x \rightarrow -2}g(x) \div f(x)\]

b. \[\lim_{x \rightarrow -2}\sqrt{f(x)g(x)}\]

c. \[\lim_{x \rightarrow -2}4f(x)+2 \div 1-g(x)+f(x)\]

Answer 2

a. 10/-2=-5
b. sqrt -20 = (2i)sqrt5
c. 4(-2) +2/1-10 -2=-4/11

Answer 3

how did you work be out

Answer 4

sqrt -20 =(sqrt -1)(sqrt20)=(sqrt -1)(sqrt4*5)=i*2sqrt5

Answer 5

O still don't get it.

Answer 6

sqrt -1= i

Answer 7

ok
