Question

f(x) = 3(x – 2)^2(x + 5) find the zeroes

Answer 1

Hints:
The graph of the function crosses the x-axes at x=-5 (from x+5=0) and is tangent to the x-axis at x=2 (from (x-2)^2=0).
Can you find the zeroes?

Answer 2

help me determine the zeroes

Answer 3

Hint:
A zero of a polynomial is where the curve crosses the x-axis or where it is tangent to the x-axis.

Answer 4

th6anks i understand now

Answer 5

would the y-intercept be 60?

Answer 6

yes, exactly.
the polynomial expands to 3x^3+3x^2-48x+60, and the constant term =60 is the y-intercept.
