Respuesta :

f(0) is a y-intercept.

f(0) = -6

we know that

The value of x is zero when the function intercept the y-coordinate

In this problem, the function intercept the y-coordinate at the point [tex] (0,-6) [/tex] only

so

[tex] f(0)=-6 [/tex]

therefore

the answer is the option

b. –6 only
