Answer
8 is WRONG! The correct answer is 7.50
Step-by-step explanation:
We have that
x²<span> − 2x − 3 = 0
Step 1
</span>isolate the variable terms
<span>x² - 2x = 3
</span>Step 2
complete the square
<span>x² - 2x + 1² = 3 + 1² </span>
<span>(x-1)² = 4
</span>
the answer is the option (x-1)² = 4
Based on the graph which models the function at x = -2 (see attachment), the corresponding y-value is y = 3.
<h3>What is a function?</h3>
In Mathematics, a function can be defined as a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.
In this scenario, there are several values (points) on the given linear graph expressed as a coordinate (x, y). Hence, the x-values on the x-axis is directly proportional to the y-values on the x-axis.
By critically observing the graph which models the function at x = -2 (see attachment), we can logically deduce that the corresponding y-value is three (3).

Answer:
C or h - 2
Step-by-step explanation:
f(a + h) = a + h - 1
f(a) = a - 1
a + h - 1 - a - 1 = h - 2
