You just have to plug in each thing:

So f(0):

3(0)^2 - 4 = -4

so its not A

f(-2) and f(2):

3(-2)^2 - 4

3(2)^2 -4

now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4

B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.

A stadium's normal ticket price is $78. As a special promotion they offer 15% off. What is the price of the discounted ticket?
meriva
You have to find out what 15% of $78 dollars is.  If you have to do this in your head and not on a calculator you can find 10%, then cut that number in 1/2 and add it to the answer.  So 10% of $78 is 7.8 so $7.80.  You can divide 7.80 by 2 and get 3.9 and add that to 7.8 which is 11.70.  So 15% of $78 is $11.70.

sweet [91]

Answer:

N(2,3)

Step-by-step explanation:

According to the Question,

  • Given that, In the triangle ABC. M is the midpoint of AB and N is the midpoint of CM And A(-1, 3), B(7-3) and C(1,6).
  • Thus, For coordinates of N. first We have to find the Coordinate of M(x,y). As Given M is the Midpoint of A(-1, 3) and B(7-3).

Thus, M(x,y) = (-1+7)/2 , (3-3)/2 ⇒ M(3,0)

  • Now, As Given, N(a,b) is the Midpoint Of C(1,6) and M(3,0).

Thus. N(a,b) = (1+3)/2 , (6+0)/2  ⇒ N(2,3)
