Answer:
B. The value is between 1 and 2
Explanation:
Im kinda unsure about this one because I haven't worked with log() alot.
But from looking at it, you are given the interval of [1, 2].
All this problem is asking is is there any value that you can plug into x to make the function equal 4?
Well lets work this out. The smallest value you have in the interval [1, 2] is 1.
So plug that in and solve.
2¹ + log₂(1) = 2 + 0 = 2
The biggest value you have in the interval [1, 2] is 2.
So plug that in and solve.
2² + log₂(2) = 4 + <em>some_fraction</em> = 4.___
Usually the log of a number is some really small fraction. So we know that at k=2, the output is a bit greater than 4.
Therefore,
at 1 ≤ k ≤ 2
2 ≤ f(k) ≤ 4.___
in word form, when k is between 1 and 2, the output of the function will give you a number between 2 and 4.___ .
Since 4 lies between those two intervals, then some values of k between 1 and 2 will give you f(k)=4.
Answer:
y=3x+5
Explanation:
when reflecting a line about the y axis the slope changes signs and when it is reflected over the x axis the y intercept and the slope change signs
Social emotional development in children have to do with their experience, expression and management of emotions. It also have to do with their ability to establish positive and rewarding relationships with others. The reasons why children need socio emotional development include the following:
1. It gives them a better understanding of their feelings and the feeling of others.
