Which exponential function goes through the points (1, 16) and (4, 128)?

djyliett [7]

Answer:

Here is the complete question (attachment).

The function which represent the given points are $f(x)=8(2)^{x}$

Step-by-step explanation:

We know that a general exponential function is like, $y=a(b)^{x}$

We can find the answer by hit and trial method by plugging the values of $(x,y)$ coordinates.

Here we are going to solve this with the above general formula.

So as the points are $(1,16)$ then for $x=1,\ y=16$

Can be arranged in terms of the general equation.

$ab^1=16$ ...equation(1) and $ab^4=128$ ...equation(2)

$a\times b=16, then\ a=\frac{16}{a}$

Plugging the values in equation 2.

We have

$\frac{16}{b} b^4=128,16\times b^3=128,b=\sqrt[3]{\frac{128}{16}} =\sqrt[3]{8}=2$

Plugging $b=2$ in equation 1.

We have $a=\frac{16}{b} =\frac{16}{2} =8$

Comparing with the general equation of exponential $a=8$ and $b=2$

So the function which depicts the above points = $y=8(2)^x$

From theoption we have B as the correct answer.

Can someone help me please

djverab [1.8K]

Answer: 6 teams

Step by step:

3 people=1 group

3+3=6

6 people taken out of 18

2 groups already

3+6=9

9 out of 18 people taken

3 groups made

9+3=12

12 out of 18 people taken

4 groups made

12+3=15

15 out of 18 people taken

5 groups made

15+3=18

18 out of 18 people taken

Answer: 6 groups made

Short step by step:

18 divided by 3 equals 6

Or

3 times 6 equals 18

I really hope that made sense
