You obtain the absolute minimum of the function when x=0. (0^4)-2 =0-2=-2. So, the lower bound of the function is -2.
The height, is 6.3 metres (to 2 dp).The height, is 6.3 metres (to 2 dp).The height, is 6.3 metres (to 2 dp).The height, is 6.3 metres (to 2 dp).
It is: 5.58
Count the numbers of digits after the decimal points (DP) in the two numbers.Add these numbers together.Calculate the product, including any trailing 0s.Place the DP so that the number of digits after the DP is the same as the sum of the digits after the DP (step 2).Thus, for 15.38 * 0.0045The first number has 2 digits after the DP, the second has 4, so sum of digits after DP is 2+4 = 6.1538*0045 = 69210.The answer must have 6 digits after the DP so you need to insert a 0 after the DP to make it .069210 which can then be simplified to .06921
They’re the ‘real value’ of a rounded number. Upper and Lower Bounds are concerned with accuracy. Any measurement must be given to a degree of accuracy, e.g. 'to 1 d.p.', or ' 2 s.f.', etc. Once you know the degree to which a measurement has been rounded, you can then find the Upper and Lower Bounds of that measurement. Phrases such as the 'least Upper Bound' and the 'greatest Lower Bound' can be a bit confusing, so remember them like this: the Upper Bound is the biggest possible value the measurement could have been before it was rounded down; while the Lower Bound is the smallest possible value the measurement could have been before it was rounded up.
4.46 is a fixed number: it has no upper nor lower bound. To 2 dp it is 4.46

1, 2, 4, 139, 278, 556 2 and 139 are prime.
1 + 2 + 4 + 139 + 278 + 556 = 980
To 4 DP, 62.1935 To 3 DP, 62.194 To 2 DP, 62.19 To 1 DP, 62.2
2 x 2 x 139
The height, is 6.3 metres (to 2 dp).The height, is 6.3 metres (to 2 dp).The height, is 6.3 metres (to 2 dp).The height, is 6.3 metres (to 2 dp).
2 x 2 x 139
the answer is 556 because 2 times 3 is 6 and take that 6 and just add it to 550 witch equals 556
