The discriminante :
b^2-4ac
1^2 - 4 * -2 * -28 = 1 - 224 = -223
When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.
-223<0, so, 2x^2+x-28 = 0 has no real solutions.
Hope that helps :)
Answer:
36
Step-by-step explanation:
because half of 12 is 6 and its square is 36
we know that
The average rate of change of the function f(x) over the interval [a,b] is equal to
in this problem
interval [a,b]---------->
for
for
substitute the values
therefore
<u>the answer is</u>
The average rate of change is equal to
Answer: A,b,e
A:Each successive output is the previous output divided by 3.
B:As the domain values increase, the range values decrease.
E:The range of the function is all real numbers greater than 0.

The tangent function has a period of π or 3.14. The period is the point where the graph touches the x-axis. The graph passes through 0 and then π. The next point is 2π. This goes on for the points nπ where n is any whole number.
