Which function grows at the fastest rate for increasing values of x?




h(x)=9.5x2

g(x)=2.5x

f(x)=8.5x+3

Respuesta :

g(x)=2.5x
is your answere

Answer:

h(x) grows in faster manner.

Step-by-step explanation:

Let f(x) and g(x) be positive for large value of x

then we say f(x) grows faster than g(x) as x → ∞  if [tex]\lim_{x \to \infty} \frac{f(x)}{g(x)}[/tex]= +∞

Let f(x) and g(x) be positive for large value of x

then we say  f(x) and g(x) grows with same rate if

as x → ∞  if [tex]\lim_{x \to \infty} \frac{f(x)}{g(x)}[/tex]= a  finite  non zero value.

Using above we can see g(x) and f(x) will grow slower than h(x) as

[tex]\lim_{x \to \infty} \frac{f(x)}{g(x)}[/tex]

[tex]\lim_{x \to \infty} \frac{9.5x^2}{2.5x)}[/tex]

therefore h(x) grows in faster manner.
