Answer:

Step-by-step explanation:

I think the first part of that is asking for the equation for the line of symmetry, although I do not have access to your drop down menu to know for sure! The axis of symmetry is the equation that splits the parabola into 2 parts that are mirror images of each other. In this type of parabola, it will be an "x = " equation. The line that splits the parabola in half is the line x = -2. The function is increasing where the y values are going up. This happens in the interval (-∞, -2].

The function is decreasing where the y values are going down. This happens in the interval [-2, ∞)

Find (fog)(x) given f(x) = 2x2-x+1 and g(x) = 4x +3

Zolol [24]

Answer:

fg(x) = 32x²+44x+16

Step-by-step explanation:

fg(x) = f[g(x)]

= f(4x+3)

= 2(4x+3)²-(4x+3)+1

= 2(16x²+24x+9)-4x-3+1

= 32x²+44x+16

Consider the function below. (If an answer does not exist, enter DNE.) g(x) = 190 + 8x3 + x4 (a) Find the interval of increase.

galben [10]

Answer:

The interval of increase of g(x) is $(-6,+\infty)$ .

Step-by-step explanation:

The interval of increase occurs when first derivative of given function brings positive values. Let be $g(x) = 190 + 8 \cdot x^{3} + x^{4}$ , the first derivative of the function is:

$g'(x) = 24 \cdot x ^{2} + 4\cdot x^{3}$

$g'(x) = 4 \cdot x^{2}\cdot (6+x)$

The following condition must be met to define the interval of increase:

$4\cdot x^{2} \cdot (x+6) > 0$

The first term is always position due to the quadratic form, the second one is a first order polynomial and it is known that positive value is a product of two positive or negative values. Then, the second form must satisfy this:

$x + 6 > 0$

The solution to this inequation is:

$x > - 6$

Now, the solution to this expression in interval notation is: $(-6,+\infty)$
