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.
Answer:3.5 miles
Step-by-step explanation:
(f*g)(x)=(x³-4x+2)(x²+2) = x⁵+2x³-4x³-8x+2x²+4=x⁵-2x³+2x²-8x+4
Answer:
3
Step-by-step explanation:
1. A - times a - equals a +, which means [-(-2)] equals (2)
2. 5- (2) equals 5 - 2
3. 5-2= 3
