Question

f(x) = x2 + 7x + 8

(a) Write f(x) in the form k(x + t)2 + r. Fill in the obtained values of k, t, r.......... how would i graph this?

Answer 1

you need to complete the square

Answer 2

f(x)=x^2+7x+(7/2)^2-(7/2)^2+8
f(x)=x^2+7x+49/4-49/4+8
f(x)=(x+7/2)^2-17/4

Answer 3

It should say write in the form of k(x-t)^2+r

Answer 4

The vertex would be at (t,r), axis of symmetry at x=t
