g(x) = -(x + 1)^2 - 3

Let's simplify this equation

g(x) = -(x^2 + 2x + 1) - 3

Distribute the negative sign

g(x) = -x^2 - 2x + 1 - 3

Combine like terms

g(x) = -x^2 - 2x - 2

The value of a = -2 and this value is LESS THAN 0

Mark all the statements that are true.

Answer:

Option A

Option C

Step-by-step explanation:

A relationship is defined as a function if and only if each element of the "domain" set is assigned only one element of the "range" set. That is, there is only one output value y assigned to each input value x.

The relation x = 3 is not a function because there are infinite output values y, assigned to the same input element x.

(3, 2), (3, 5) (3, 9) (3,10000)

Then the option A is true

Option C is also true, the equation of the line shown is

$x = 3$

The rest of the options are false because x = 3 is not a function

The graph of a linear function is shown on the grid. (-3,3.6) (5,2) What is the rate of change of y with respect to x for this f

lilavasa [31]

Answer:

rate of change = -0.32

Step-by-step explanation:

Rate of change = slope,m

$m = \frac{y2 - y1}{x2 - x1} \\ m = \frac{3.6 - 2}{ - 3 - 2} \\ m = \frac{1.6}{ - 5} \\ m = \frac{ - 0.32}{1}$

Area of the shaded region = Area of a square - Area of a circle

Side of a square = 2r
Area of a square = (2r)² = 4r²

Area of a circle = πr²

Area of the shaded region = 4r² - πr² = r²(4-π)

Evgesh-ka [11]

By using exponent, it can be verified that

$(2.9 \times 10^5) \times (3.4 \times 10^3)$ in standard form is $9.86 \times 10^8$
