At what point does the graph of y=9x(x is exponent) cross the y-axis?

uysha [10]

Answer:

-The graph crosses the y-axis at the point (0,0)

None of the given options is correct

A graph crosses the y-axis at the point (0,y).This means that the graph will cross the y-axis when x-=0

To find the point where the graph crosses the y-axis,substitute x=0 into the given equation y-9x

substitute x=0 into the equation y-9x to find the corresponding value of y

That is,

y=9(0)

y=0

therefore the graph crosses the y-axis at the point (0,0)

Which polynomial function has zeros at 2, −4, and 1?

LuckyWell [14K]

Answer:

y = (x - 2)(x + 4)(x - 1)

Step-by-step explanation:

Given the zeros of a function say x = a and x = b, then

The factors are (x - a) and (x - b) and

y = (x - a)(x - b)

Given the zeros are x = 2, x = - 4, x = 1, then

the factors are (x - 2), (x - (- 4)) and (x - 1), that is

(x - 2), (x + 4), (x - 1) , thus

y = (x - 2)(x + 4)(x - 1)

Which sentence is NOT a geometric progression?

DIA [1.3K]

c) 3, 6, 9 12 is NOT a geometric progression

<h3>Further explanation </h3>

Geometry sequences are series of numbers that have a constant ratio

or can be interpreted:

Each number is obtained by multiplying the previous number by a constant

The sequence can be:

a, ar, ar², ar³, ... etc.

Can be formulated

$\large {\boxed {\bold x_n = ar ^ {n-1}}}$

where:

a is the first term, and

r is the common ratio

So we have to see the series has the same ratio or not

a. $\dfrac{5}{1}=\dfrac{25}{5}=5\to \rm geometric\:progression$

b. $\dfrac{8}{4}=\dfrac{16}{8}=2\to \rm geometric\:progression$

c. $\dfrac{6}{3}\neq \dfrac{9}{6}\to \rm not\:geometric\:progression$

d. $\dfrac{6}{2}=\dfrac{18}{6}=3\to \rm geometric\:progression$
