Which statement about the function f(x)=|x+3| is true?
Stels [109]

The given function f(x) = |x + 3| has both an absolute maximum and an absolute minimum.

What do you mean by absolute maximum and minimum ?

A function has largest possible value at an absolute maximum point, whereas its lowest possible value can be found at an absolute minimum point.

It is given that function is f(x) = |x + 3|.

We know that to check if function is absolute minimum or absolute maximum by putting the value of modulus either equal to zero or equal to or less than zero and simplify.

So , if we put |x + 3| = 0 , then :

± x + 3 = 0

±x = -3

So , we can have two values of x which are either -3 or 3.

The value 3 will be absolute maximum and -3 will be absolute minimum.

Therefore , the given function f(x) = |x + 3| has both an absolute maximum and an absolute minimum.

I just stuck. Someone explain.
KatRina [158]

If there are parentheses you add the exponent on the outside to the exponents inside that belong to a variable.

For the three you would just cube it regularly, but for the x you would add the 3 to the 2 that is already on the x

Plz help number 3d ( can you pls show ur steps of how you got the answer)

Answer:

(\frac{13}{16},-\frac{3}{8})

Step-by-step explanation:

Midpoint of a segment with the given endpoints (x_1,y_1) and (x_2,y_2) is defined by,

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

In this question endpoints of the segment are,

Q(-\frac{3}{8},\frac{1}{8}) and R(2,-\frac{7}{8})

Coordinates of the midpoint will be,

(\frac{-\frac{3}{8}+2}{2},\frac{\frac{1}{8}-\frac{7}{8}}{2})

= (\frac{13}{16},-\frac{3}{8})

Therefore, coordinates of the midpoint are (\frac{13}{16},-\frac{3}{8}).
