<h2>1)</h2>
This must be true for some value of x, since we have a quantity squared yielding a positive number, and since the equation is of second degree,there must exist 2 real roots.
<h2>2)</h2>
Well he started off correct to the point of completing the square.
It has to be A because of the other letter
Answer:
A. f(x) = -4|x + 2| + 3
Step-by-step explanation:
An absolute value graph is a v-shaped graph whose equation has the form y = a| x - h| + k where (h,k) is the vertex. On the graph the vertex is (-2,3). This means its equation is y = a| x --2| + 3. It simplifies to y = a|x+2|+3. To find a, look at the answer options. Each option has 4 or -4. Since the graph faces downward, it has a negative leading coefficient of a = -4. The equation is y = -4|x+2|+3
Answer:
B) -4 - 12i
Step-by-step explanation:
(3-4i)+(-7-8i) = 3 -4i - 7 - 8i
= 3 - 7 - 4i -8i
= -4 - 12i
