Which graph best represents the function f(x) = 3(1.5)x?
jok3333 [9.3K]

Answer:

B). graph of increasing exponential function going through point (0, 3)

Step-by-step explanation:

Given function is f\left(x\right)=3\left(1.5\right)^x

Now we need to find about which of the given choices best describes the given function. Where given choices are:

A). graph of increasing exponential function going through point 0, 2

B). graph of increasing exponential function going through point 0, 3

C). graph of increasing exponential function going through point 0, 1

D). graph of increasing exponential function going through point 0, 4

plug x=0 into given function

f\left(x\right)=3\left(1.5\right)^x

f\left(0\right)=3\left(1.5\right)^0=3(1)=3

Hence graph passes through point (0,3).

growth factor 1.5 is greater than 1 so that means it is increasing function.

Hence correct choice is:

B). graph of increasing exponential function going through point (0, 3)

Choose Yes or No to tell if the fraction 3 5 will make each equation true. 7 20 + □ = 19 20 Choose... □ + 3 10 = 3 15 Choose...
OleMash [197]

Answer:

True ; false ; False ; true

Step-by-step explanation:

Equation 1:

7 20 + □ = 19 20

19 / 20 - 7/20

(19 - 7) / 20

12/ 20 = 3/5

Equation 2:

□ + 3 10 = 3 15

3/5 + 3/10

(6 + 3) / 10 = 9/10

Equation 3:

1 2 + 2 3 = □

1/ 2 + 2/3

(3 + 4) / 6

7 / 6

Equation 4:

1 10 + 1 2 = □

1/10 + 1/2

(1 + 5) / 10

6 / 10 = 3/5

F(x) = x+2
g(x) = 2x+1

we \: have \: to \: find \: (fog)(x)
= f(g(x))
=> (fog)(x) = (2x+1)+2
= 2x+3
