Answer:
Step-by-step explanation:
(5f-3)(-2)
-10f + 6 = 0
f= 6 + 10
f = 16
Answer:
100 x 4 = 400 - 91 = 309
Step-by-step explanation:
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.
