Answer 2

What value is the y-intercept (i.e. at which value does the cross the y-axis)

Answer 3

that will be the value of the constant of your equation.. so which of the options given to you best matches the value of your constant?

Answer 4

for x=0
y[or f(x)]=-5

try putting c=0 in the options nd the one in which f(x) comes -5 is the answer :)
