Question

What can you say about the values of the coefficients a, b, and c in the function f(x)= ax^2+bx+c if the y intercept is 10?

Answer 1

a can be positive or negative

Answer 2

C equals 10 and a and b can be either positive or negative

Answer 3

b will be the sum or difference of two integers that multiply to get 10.

Answer 4

y-intercept: when a curve intercepts Y-axis, its abscissa becomes "0" (x=0)

so, the point on the graph is (0,10)
substitute x=0 and y=10
you find c=10

This answer had nothing to do with "a" and "b" so, nothing can be said about them
