The x-coordinate of the vertex can be found by -b/2a where the equation is ax^2 + bx + c
3x^2 + 6x + 3
b is 6, and a is 3
-b/2a = -6/2(3) = -6/6 = -1
The x-coordinate of the vertex is -1. To find the y-coordinate plug the x-coordinate into the equation and solve for y.
f(-1) = 3(-1)^2 + 6(-1) + 3
= 3(1) - 6 + 3
= 3 - 6 + 3
= 0
The y-coordinate is 0
The vertex is (-1, 0)
Area = 3 * 1/2 * 10 * 12 + 1/2 * 12 * 8 = 180 + 48 = 228 answer
Answer:
0
Step-by-step explanation:
You first multiply -2(-2) which will be 4 since a negative times a negative is a positive. Next you subtract 4 and -4 which is 0. Lastly you bring down the y which is equal to 0.
Answer:
The zeros of the given function are -9,-1 and 12.
Step-by-step explanation:
The given function is
It is given that the x-intercept of the graph is -9, therefore -9 is a zero of the function.
Since -9 is the zero of the function, therefore (x+9) is a factor of f(x). Use synthetics method or long division method to divide the function by (x+9).
Use zero product property and quote each factor equal to 0.
Therefore zeros of the given function are -9,-1 and 12.
