• Question:2
Give a rough estimate (by rounding off to nearest hundreds) and
also a closer estimate (by rounding off to nearest tens):
(a) 439 + 334 + 4, 317 (b) 1,08, 734 - 47,599 (c) 8325 - 491
• (d) 4, 89, 348 - 48, 365, Make four more such examples.
• (a) 439 + 334 + 4317
Rounding off to nearest hundreds, 439, 334, and 4317 may be
rounded off to 400, 300, and 4300 respectively.
• 400+300+4300=7000
Rounding off to nearest tens, 439, 334, and 4317 may be rounded
off to 440, 330, and 4320 respectively.
440+330+4320=5090
• (b) 1,08,734 - 47,599

step-by-step explanation:

answer:

c) the x-coordinate of the center of the circle increases by 3

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1
