Answer: (-2, -5), (-1, -8), (0, -9), (1, -8), (2, -5)
Step-by-step explanation:
f(-2)=(-2)^2-9
f(-2)=4-9
f(-2)=-5 ==> (-2, -5)
f(-1)=(-1)^2-9
f(-1)=1-9
f(-1)=-8 ==> (-1, -8)
f(0)=0^2-9
f(0)=0-9
f(0)=-9 ==> (0, -9)
f(1)=(1)^2-9
f(1)=1-9
f(1)=-8 ==> (1, -8)
f(2)=(2)^2-9
f(2)=4-9
f(2)=-5 ==> (2, -5)
To get the answer do this:
2.5% of what is 2.21
2.5%x = 2.21
2.5/100x = 2.21
0.025x = 2.21
divide both sides by 0.025
0.025x/0.025 = 2.21/0.025
x = 88.4
