Which graph represents the function f(x)= 0.2^x + 3

Dennis_Churaev [7]

The third graph or bottom left graph represents $f(x) = 0.2^{x} + 3.$

Step-by-step explanation:

Step 1:

To determine which of the given graphs represents the equation $f(x) = 0.2^{x} + 3$ , we substitute some values in the place of x.

When $x=0,$ $f(x) = 0.2^{x} + 3, f(0) = 0.2^{0} + 3= 4.$

Anything with an exponent of 0 will equal 1.

So the graphs on the right side cannot be the answers.

Step 2:

Now we substitute another value to determine which graph represents $f(x) = 0.2^{x} + 3.$

When $x=1,$ $f(x) = 0.2^{x} + 3, f(1) = 0.2^{1} + 3= 4.2.$

The value of f(x) when $x=1$ is lesser than the value of f(x) when $x =0.$

So the third graph or bottom left graph represents $f(x) = 0.2^{x} + 3.$

For the sequence <img src="https://tex.z-dn.net/?f=a_%7Bn%7D%20%3D%202n%2F%28n%2B1%29" id="TexFormula1" title="a_{n} = 2n/(n+1)"

Nat2105 [25]

Answer:

$a_{10}=\frac{20}{11}$

Step-by-step explanation:

The formula for nth term of a the sequence is given as $a_n=\frac{2n}{n+1}$

<u>Finding the 10th term means finding $a_{10}$ , which means to plug in 10 into n, in the nth term formula.</u>

$a_{10}=\frac{2(10)}{(10)+1}=\frac{20}{11}$
