You would subitute -2 for x in the equation
f(-2)=x^2-6
PEMDAS so exonents
-2^2-6
negative times a negative= positive
4-6
f(-2)=-2
f(x) means that you subsitute x for x in the equation exg
f(1)=x+2 means f(1)=1+2
f(4)=x+2 means f(4)=4+2
The first one is 4•7 I believe
Answer:
56 ft^2
Step-by-step explanation:
Answer:
10 feet
Step-by-step explanation:
a^2+b^2=c^2
