Question

Find the critical numbers (x-values) of the function y equals 2 x to the power of 5 plus 5 x to the power of 4 minus 19. Enter your answers as a comma-separated list. Round answers to 2 decimal places, if necessary.

Answer 1

Answer:

$x=0,x=-2$

Step-by-step explanation:

From the question we are told that:

$y=2x^5+5x^4-19$

Generally the equation if differentiated is mathematically given by

$y'=10x^4+20x^3-0$

Where

y'=0

$10x^4+20x^3=0$

Factorizing,We have

$x=0,x=-2$

Therefore

The critical points are

$x=0,x=-2$
