Given that f(x) = 2x + 1 and g(x) = the quantity of 3x minus 1, divided by 2, solve for g(f(3)). 5 7 9 10

AlladinOne [14]

The correct answer is 10.

In order to evaluate any composite function, you need to first put the value in for the inside function. In this case f(x) is on the inside along with the number 3. So, we input 3 in for x in f(x).

f(x) = 2x + 1

f(3) = 2(3) + 1

f(3) = 6 + 1

f(3) = 7

Now that we have the value of f(3), we can stick the answer in for the outside function, which is g(x).

g(x) = (3x - 1)/2

g(7) = (3(7) - 1)/ 2

g(7) = (21 - 1)/2

g(7) = 20/2

g(f(3)) = 10

Which would be a good estimate for the tax on $97.95 if the tax is 9.5%?

Ahat [919]

It would be $10. There is a formula to this "madness". Divide $97.95 by 9.5%. Ignore the rest of the numbers. (I'm pretty sure it has like 7 or 8, but I only went up to 3. Just make sure you have have the whole number, $10). Hope this helps.

What is the common difference, d, in the arithmetic sequence defined by the formula below? an=2n+1

marishachu [46]

<h3>Answer:</h3>

d = 2

<h3>Solution:</h3>

We are given that the arithmetic progression is defined by :

➝ 2n + 1

Therefore, 

For first term

➙ n = 1

➝ 2 × 1 + 1

➝ 2 + 1

➝ 3

For second term

➙ n = 2

➝ 2 × 2 + 1

➝ 4 + 1

➝ 5

Common difference

➙ 2nd term - 1st term

➝ 5 - 3

➝ 2

<h3>More information:</h3>

The difference between the successive term and the preceding term is the difference of an arithmetic progression. It is always same for the same arithmetic progression.
