Given:
The graph of a quadratic function passes through the points (5,31) (3,11) (0,11).
To find:
The equation of the quadratic function.
Solution:
A quadratic function is defined as:
...(i)
It is passes through the point (0,11). So, substitute
in (i).


Putting
in (i), we get
...(ii)
The quadratic function passes through the point (5,31). So, substitute
in (ii).

Divide both sides by 5.
...(iii)
The quadratic function passes through the point (3,11). So, substitute
in (ii).
Divide both sides by 3.
...(iv)
Subtracting (iv) from (iii), we get




Putting
in (iv), we get



Putting
in (ii), we get
Therefore, the required quadratic equation is
.
Okay lets go down the list. It's not right since 20²+99²=10201 √10201=101 and you said a is wrong it's have to be B. obtuse
Number 2 is 6
i dont know number 3
<span> number 4 is _x-intercept = -12/11 = -1.09091 y-intercept = -12/4 = -3
</span>number 5 is x=12 ,<span>y=<span>−8</span></span><span>y=<span>-<span>8</span></span></span>
