Consider the quadratic function. ()=2−8−5 What are the values of the coefficients and the constant in the function? : a = –1, b = –8, c = –5 a = 1, b = –5, c = –8 a = 1, b = –8, c = –5 a = –1, b = –5, c = 8

Correct option c). a= 1 , b= -8 , c =-5 .

Step-by-step explanation:

We have the following quadratic equation : f(x) =

In algebra, a quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term. Equation :

Equation can be written as : , on comparing to equation  we get:

∴ Correct option c). a= 1 , b= -8 , c =-5 .

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
