# Math Help - Find point or points on the graph where the tangent line is horizontal.

1. ## Find point or points on the graph where the tangent line is horizontal.

Find point or points on the graph where the tangent line is horizontal.

f(x) = 6x^2+2x-7

h(s) = x^3-2x^2+4x-9

2. $f'(x) = 0
$

and

$h'(s) = 0$

and solve, this is because the slope at the horizantal is equal to zero always.

Which graph? You give two functions. And surely you mean h(x), not h(s).
