Respuesta :

In the interval x = 0 to 2,
the 5^x graph goes from y=1 to y=25
and the 5x graph goes from y=0 to y=20

Thus,
A Y=5X GROWS GROWS SLOWER THAN Y=5^X

Answer:

The correct option is A.

Step-by-step explanation:

The given functions are

[tex]y=5x[/tex]

[tex]y=5^x[/tex]

The slope of a function is defined as

[tex]m=\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

In first function, at x=0

[tex]y=5(0)=0[/tex]

At x=2

[tex]y=5(2)=10[/tex]

Growth rate of first function is

[tex]m_1=\frac{10-0}{2-0}=5[/tex]

Therefore the growth rate of y=5x is 5 from x = 0 to x = 2.

In second function, at x=0

[tex]y=5^(0)=1[/tex]

At x=2

[tex]y=5^(2)=25[/tex]

Growth rate of first function is

[tex]m_1=\frac{25-1}{2-0}=12[/tex]

Therefore the growth rate of y=5^x is 12 from x = 0 to x = 2.

So we can say that y=5x grows slower than y=5^x.

Therefore option A is correct.
