critical f(x)=1-5x — step-by-step solution

⚠ 5x is read as the product 5*x: for a power, write 5^x

A polynomial is differentiable on ℝ: its critical points are the zeros of its derivative

⇥Let's perform the differentiation:

\frac{d}{d x} (1 - 5 x)

⇥

0 + \frac{d}{d x} (- 5 x)

⇥

-5

The constant derivative

-5

is never zero: there is no critical point

▶Critical points:

x \in \emptyset
