f(x) = 3x² - 1
f(-2) = 3(-2)² - 1
f(-2) = 3(4) - 1
f(-2) = 12 - 1
f(-2) = 11
f(x) = x < 1
f(-2) = -2 < 1
f(x) = x + 2
f(-2) = -2 + 2
f(-2) = 0
f(x) = x ≥ 8
f(-2) = -2 ≠ 8
The earth is approximately 9.2*10^7 farther than mercury
Answer:
x - 2 ≥ 0
Step-by-step explanation:
The expression under the square root cannot be negative, thus
x - 2 ≥ 0 , that is
x ≥ 2
Step-by-step explanation:
or, 3(5-p)-2(5+p)=3(p+1)
or, 15-3p-10-2p=3p+3
or, 5-5p=3p+3
or, 5-3=3p+5p
or, 2=8p
or, 2/8=p
or, 1/4=p
