a. The graph is concave up in the interval 0 ≤ x ≤ +∞

b. The graph is concave down in the interval -∞ ≤ x ≤ 0

To answer the question, we need to know what intervals are

<h3>What are intervals?</h3>

Intervals are range of values in which a function is valid. It can either be the range of values of input or output of the function.

<h3>a. Interval where the graph is concave up</h3>

From the graph, we see that the function is concave up in the interval 0 ≤ x ≤ +∞

So, the graph is concave up in the interval 0 ≤ x ≤ +∞

<h3>b. Interval where the graph is concave down</h3>

From the graph, we see that the function is concave down in the interval -∞ ≤ x ≤ 0

So, the graph is concave down in the interval -∞ ≤ x ≤ 0

Find the equation for the line passing through the point (−3,−3) and perpendicular to the line whose equation is −1x+2y+2=0.

RSB [31]

First we have to figure out the slop of the given equation:
-1x+2y+2=0
y=1/2x - 1

So the slope is 1/2. A line perpendicular to this line has a slope of the negative reciprocal of this slope. So the slope of the line you want to find is -2.

So: y +3 = -2(x+3).

And you can expand into the form that you want (or just keep it this way). :)

PLEASE HELP!!!

The product of the given polynomials is 12 $x^{6}$ y+8x² $y^{4}$ .

The given polynomial is 4x²y(3x⁴+2y³).

We need to find the product of the given polynomials.

<h3>How to multiply the polynomials?</h3>

To multiply two polynomials: multiply each term in one polynomial by each term in the other polynomial. add those answers together, and simplify if needed.

Now, using the distributive property we get 4x²y(3x⁴+2y³)=4x²y×3x⁴+4x²y×2y³

=12 $x^{6}$ y+8x² $y^{4}$

Therefore, the product of the given polynomials is 12 $x^{6}$ y+8x² $y^{4}$ .
