If they're both equal $20 but there is many different ways to answer this like 19 plus 21
When we try to solve for f(-2), we are trying to find the range of the point that has a domain of -2. On the graph, when x equals -2, f(x) equals 2. The blank is 2.
Measure of angle 2 is 77. hope this helped.
we have

we know that
The x-intercept is the value of x when the value of the function is equal to zero
so
in this problem
Find the roots of the function
equate the function to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares

Square root both sides






therefore
<u>the answer is</u>
the x-intercepts are the points
and 
What you could do it is. Start adding numbers and once you get close to
6 numbers See if you are close to 51 and switch around the numbers to make it equal 51 hope this helps
