H(x)=2x3 – 3 Find h(2)

1 answer:

8 0

When it tells you to find h(2), that means you plug in 2 for x.
If 2x^3 (to the third power)
2(2)^3-3

1. PEMDAS, exponents first
2^3=8

2. multiply
8x2=16

3. subtract
16-3=13

Hope this helps!

Fractional index means "xth root of". Negative index means a fraction. So together, what it really means is:

$\frac{1}{\sqrt[5]{32}} = \frac{1}{2}.$

find the sum and product of the zeros of the quadratic polynomial are -1/2 and -3.what is the quadratic equation

11111nata11111 [884]

Answer:

Step-by-step explanation:

let sum of zeros=s

and product of zeros=p

then quadratic equation is x²-sx+p=0

x²-(-1/2)x+(-3)=0

x²+1/2 x-3=0

Given line AB and point O on that line, any ray that can be drawn with its endpoint at O can be put into a one- to-one correspon

natima [27]

Answer:

Protractor

Step-by-step explanation:

A POSTULATE, LAW OR THEORY SHOULD NEVER BE ALTERED

∴ The protractor postulate states that the measurement of an angle between two rays can be designated as a unique number, and this number would be between 0 and 180 degrees, Hence for every angle A, there corresponds a positive real number less than or equal to 180. This postulate guarantee the use of a protractor to measure angles.

Hence, Given line AB and point O on that line in such a way that any ray that can be drawn with its endpoint at O can be put into a one- to-one correspondence with the real numbers between 0 and 180 is a statement that explains Protractor's Postulate.

Please help someone

Answer:

(-2, ∞)

Step-by-step explanation:

A function is "increasing" when its graph goes up to the right, the slope is positive. At a turning point (maximum or minimum), the function is neither increasing nor decreasing.

<h3>Increasing interval</h3>

The graph has a minimum at x = -2. To the left of that point, the graph goes up to the left, which is the same as down to the right (decreasing).

To the right of x = -2, the graph goes up to the right (increasing). It continues to increase for all values of x > 2. The interval where the function is increasing is said to be ...

-2 < x < ∞

The lack of "or equal to" tells you the interval is "open" and is delimited by parentheses in interval notation:

increasing; (-2, ∞)
