Answer:
(-6,8)
Step-by-step explanation:
8+x2=2 4+y2=12
x2= -6 y2= 8
Use the squeeze theorem; if
1 - <em>x</em> ²/4 ≤ <em>u(x)</em> ≤ 1 + <em>x</em> ²/2,
then taking the limit on each part as <em>x</em> approaches 0 gives
1 ≤ lim [<em>x</em> → 0] <em>u(x)</em> ≤ 1
and so the limit of <em>u(x)</em> as <em>x</em> → 0 is simply 1.

Answer:
Step-by-step explanation:
<h3>Given AP </h3>
<h3>To find</h3>
<h3>Solution</h3>
- a₁₂ = a + 11d = 62
- a₂₀ = a + 19d = 102
<u>Subtract the first equation from the second one:</u>
<u>Find a:</u>
- a + 11*5 = 62
- a = 62 - 55
- a = 7
<u>Find the sum of the first 20 terms:</u>
- S₂₀ = 1/2*20(a + a₂₀) = 10(7 + 102) = 10(109)= 1090
Step-by-step explanation:
a. the domain ={-3, 0, 1, 2}
the range = {6, 2, 0, -3}
the relation is a function
b. the domain = {-1, 2, 1}
the range = { -4, 8, 4}
the relation is not a function
