20 pts and let f(x)=15/1+4e−0.2x . what are the asymptotes of the graph of f(x) ? select each correct answer. y = 15y = 4y = 0y=−0.2

y=0

y=15

Step-by-step explanation:

y = 0

Step-by-step explanation:

Given function,

Which is an exponential function,

And, for an exponential function there is only horizontal asymptote exists,

For the horizontal asymptote,

Thus, Third option is correct.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
