Following the example given where "square, then subtract 5" refers to squaring the variable x and then subtracting 5 from it.
f(x) = x² - 5
The "rule" we must then express in function notation is "subtract 6, then square". The rule appears to suggest that the number 6 is being subtracted from the variable x. Then the entire expression is squared, resulting in the following function:
f(x) = (x - 6)²
Let's take a look at the triangles ABC and DCB
1. angles : B=C=90° because they are right triangles (AB perpendicular to BC and DC perpendicular to BC)
2. AC=BD (given)
3. BC is in common (the two triangles have it, you can say it like BC=BC)
So we proved that by SAS(side angle side), the triangles are congruent ABC= DCB
Since the triangles are congrueny, all their sides are equal so we can say that AB=DC
Answer:f ( x - 1 ) = 3x² - 5x - 7

Answer:
$377, $6177
Step-by-step explanation:
Sounds like simple interest (interest added to the account at the end of each year).
Here the interest earned would be:
i = $5800*0.065*1, where the '1' represents 1 year. This comes out to $377.
Adding this to the $5800 principal, we get the end-of-year amount $6177.
