Question

f(x)= ax 2 + bx + c identify the value of a,b,c

Answer 1

we have the following:

$f(x)=ax^2+bx+c$

therefore:

c.

$\begin{gathered} f(x)=8x^2+9-x \\ f(x)=8x^2-x+9 \\ a=8 \\ b=-1 \\ c=9 \end{gathered}$

d.

$\begin{gathered} f(x)=-2-7x^2+1 \\ f(x)=-7x^2-1 \\ a=-7 \\ b=0 \\ c=-1 \end{gathered}$
