Give an example of a quadratic function has a maximum value. Explain how you know it has a maximum algebraically

Mathematics

tankabanditka [31]3 years ago

Answer:

y = -x²  

Step-by-step explanation:

The simplest quadratic I can think of is

y = -x²

It must have a maximum because as

x ⟶  -∞, y ⟶ -∞ and as

x ⟶ +∞, y ⟶ -∞.

There must be a maximum somewhere between the two extremes.

Find the measures of EAF DAE and CAD
sdas [7]
You have to build an equation to find the answer,

angles in a straight line add upto 180° 
so your equation would be,

12x+30°=180°
      -30    -30
=12x=150°
   ÷12  ÷12
=x=12.5°

now find the measures of the angles by using 12.5 as x.

angle EAF= 2x
                 =2×12.5
                 =25° degrees

angle DAE= 4x
                 =4×12.5
                 =50°degrees

angle CAD=6x
                 =6×12.5
                 =75°degrees

check,
30+25+50+75=180°degrees

hope this helps.......
