Answer:

See attached image

Step-by-step explanation:

The graph of $y\geq (x+2)^2$ is not the one shown on the picture. Although the highlighted are (above the curve) is correct, since that corresponds to the y-values larger than those of the parabola, the problem is that in the picture given, the actual trace of the parabola (which corresponds to the equality $y=(x+2)^2$ , is shown with dotted trace - which by convention indicates that the trace is NOT included.

Since the inequality symbol in our inequality DOES contain the equal sign (larger than OR EQUAL to), the parabola's trace should be represented with a solid line. (see attached image)

What can you say about the y-values of the two functions f(x)=3^(x)-3 g(x)=7x^2-3

Mice21 [21]

Answer: g(x) has the smallest possible y-value of -3

Step-by-step explanation:

f(x) = 3ˣ - 3 This is an exponential graph shifted down three units. So, it has an asymptote at y = -3, which means it approaches -3 but does not touch it.

Range: y > 3 (-3, ∞)

g(x) = 7x² - 3

⇒ g(x) = 7(x - 0)² - 3 This is a parabola with vertex at (0, -3)

Range: y ≥ 3 [-3, ∞)

Type the correct answer in each box. If necessary, use / for the fraction bar. A bag contains 5 blue marbles, 2 black marbles, a

konstantin123 [22]

Answer:

Step-by-step explanation:

Problem One

Blue = 5

Black =2

Red = 3

First of all there are 10 marbles, 2 of which are black.

That means that 8 others are not black

You can draw any one of the 8.

P(not black) = 8/10 = 4/5

Problem Two

There are 10 marbles in all

3 of them are red.

P(Red) = 3/10

(1.2×10^2) + (3.04×10^5)

PSYCHO15rus [73]

(1.2×10^2) + (3.04×10^5)

They must be to the same power to add

3.04 *10^5 to change to the 2nd power (5-2=3) move the decimal 3 places to the right = 3040. * 10^2

1.2 * 10^2 + 3040 *10^2=

add the numbers keep the exponents the same

3041.2 * 10^2

there can only be 1 number before the decimal in scientific notation so we need to move the decimal 3 places to the left, which adds 3 to the exponent

3.0412 * 10 ^ (2+3)

3.0412 * 10^5
