Question

Given: f(x) = {7x+3 if −2 < x < 4 and 4x+9 if 4 < x < 8 Find the values of f(x) at x = -1 and 6.

Answer 1

Answer:

given:::

α+β=αβ

-b/a+c/a

-b=c

-(-27)=3k2

27=3k2

k2= 27/3

k2= 9

k= 3

given , sum of 0s = product of 0s

= -b/a = c/a

dividing both sides by a,

-b =c

27=3k2

k2=9

k=3
