Determine which function has the greatest rate of change as x approaches infinity.

A). f(x) = 2x − 8
B). g(x) = 5x2 − x + 7
C). h(x) = 4x − 6
D). There is not enough information to determine the answer.

Respuesta :

Answer:  C). h(x) = 4x − 6

Step-by-step explanation:

all the others were incorrect

The function which has the greatest rate of change as x approaches infinity is g(x) = 5x2 − x + 7.

What is rate of change?

The rate of change of a function is the change in the value of one variable or quantity with respect to change in value of another variable.

The function given in the problem are,

  • A). [tex]f(x) = 2x - 8[/tex]
  • B). [tex]g(x) = 5x^2 -x + 7[/tex]
  • C). [tex]h(x) = 4x - 6[/tex]

It has to determine which function has the greatest rate of change as x approaches infinity. For this let a number, (say 5) and check the values of all the function on this number.

For the first function at x=5,

[tex]f(5) = 2(5) - 8\\f(5) = 10 - 8\\f(5)=2[/tex]

For the second function at x=5,

[tex]g(5) = 5(5)^2 -5 + 7\\g(5) = 125 -5 + 7\\g(5) = 127[/tex]

For the third function at x=5,

[tex]h(5) = 4(5) - 6\\h(5) = 20 - 6\\h(5)=14[/tex]

Here, the value of the second function is greater when we compare the values of all the function.

Thus, the function which has the greatest rate of change as x approaches infinity is g(x) = 5x2 − x + 7.
