Given the functiom y=x^4 -8x^2+16. on which intervals is the function increasing

Step-by-step explanation:

Find the derivative of the function

The function is increasing when so solve the inequality

You can see from the graph that the function increases for

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
