Verizon [17]

Answer:

c.  Weight is input, height is output

Step-by-step explanation:

Thus, value of Height is depend on the value of Weight.

Thus, Weight is input variable and Height is output variable.

Hence option (c) is correct.

Further,

The variable that we can change is called the Input variable.

 The Output variable depends upon the input variable, as we change the value of the input variable the value of the output variable is also get changed.

Y= 2x^3 - 15x^2 + 36x - 20 find turning points and show working out
Murljashka [212]

Given:

The function is:

y=2x^3-15x^2+36x-20

To find:

The turning points.

Solution:

We have,

y=2x^3-15x^2+36x-20

Differentiate the given function with respect to x.

y'=2(3x^2)-15(2x)+36(1)-(0)

y'=6x^2-30x+36

y'=6(x^2-5x+6)

For turning point, y'=0.

6(x^2-5x+6)=0

x^2-3x-2x+6=0

x(x-3)-2(x-3)=0

(x-3)(x-2)=0

Using zero product property, we get

x-3=0 and x-2=0

x=3 and x=2

Therefore, the turning points of the given function are at x=2 and x=3.
