Answer:
(-2, -1)
Step-by-step explanation:
This is a quadratic equation in standard form, and a = 1, b = 4 and c = 3.
The x-coordinate of the vertex is given by the formula
-b -4
x = --------- which here has the numerical value x = -------- = -2
2a 2
Finally, we evaluate y=x^2+4x+3 at x = -2 to find the y-coordinate of the vertex:
y = (-2)^2 + 4(-2) + 3 = -1
The vertex is at (-2, -1).
You would be able to find this out using the calculator
Growth means a base for exponentiation bigger than 1 (in absolute value), otherwise it's decay.
Only the first choice has a base biggerthan 1. The last choice is equivalent to
so has a base less than 1.
Answer: A
15% of 60 = 9.
15/100 • 60 = 9.
I hope that helped! c:
3 minus 24 is negative 21
