To solve the equation hj2 based on the information provided, we need to understand what the notations mean. Let’s break down the components:
– The expression hx = 3x + 1: This indicates a function h of x that yields 3x + 1 as its output.
– The expression jx = 2x: This indicates a function j of x that yields 2x as its output.
Next, we analyze the term hj2. Since j2 is our first step, we will first compute j(2):
j(2) = 2 * 2 = 4
Now, we can substitute this result into the function h:
h(j(2)) = h(4) = 3(4) + 1 = 12 + 1 = 13
Thus, the value of hj2 is 13.
In summary, based on the definitions of the functions provided, we find:
hj2 = 13
