Answer:
39
Step-by-step explanation:
This weird notation just means we are going to put one equation inside the other, and then solve.
Makes more sense when you write it like this:
g ( f ( x ) )
To solve, we are going to take the 3, plug it into the f ( x )
g ( f ( 3 ) )
^ This makes it a lot easier to understand what we have to do.
----------------------------------------------------------------------------------------------------------
Ok, so now we evaluate f ( x ) at 3.
4 ( 3 ) - 2
f( x ) = 10
Then we plug it into g ( x )
4 ( 10 ) - 1
= 39
Here's how it looks in total:
4 ( 4 ( 3 ) - 2 ) - 1 = 39
Slightly more complicated, but that's why i broke it down step by step.
This is an arithmetic series, so we know, that:
Sum = (First term + Last term) * Number of terms /2
Here we have:
First term = 33
Last term = 104
Number of terms = 104 - 33 + 1 = 72
and
Starting with 5^0 (since in PEMDAS, we have parenthesis, exponents, multiplication, division, addition, and subtraction, and exponents come before multiplication), we know that anything to the power of 0 equals 1. Therefore, 5^0=1. Next, for 2^1, anything to the power of 1 means it's that number, so 2^1=2. Note that for 2^3 (and for most exponents), however, it's 2 multiplied by itself 3 times, or 2*2*2=8. Since 5^0=1 and 2^1=2, 5^0*2^1=1*2=2
