Consider f(x) = bx. which statement(s) are true for 0 < b < 1? check all that apply. the domain is all real numbers. the d
NeTakaya

The true statement for f(x)=b^x is the function is always decreasing function.

We have given,

f(x)=b^x where 0<b<1

<h3>What is the domain?</h3>

Domain is all possible values of x for which any function is defined

We can select any values of x for which function

It will be defined for all real x

So, the domain is (-\infty,\infty)

The range is all possible values of y for which x is defined

we are given that b is positive

The value of the function will always be positive

So, the range is  (0,\infty)

y>0

The x-intercept:

Set f(x)=0 and then we can solve for x

f(x)=b^x=0

x is undefined

The x-intercept does not exist

Increasing or decreasing:

Since, 0<b<1

The b is a positive value less than 1

As we increase the value of, b^x will keep decreasing

This is decreasing function

Find the equation of the parabola with focus at (3,3) and a directrix of y=1
vodomira [7]

Answer:

−4y

Step-by-step explanation:

Since the directrix is vertical, use the equation of a parabola that opens up or down.

(x−h)2=4p(y−k)

Find the vertex.

The vertex (h, k) is halfway between the directrix and focus. Find the y coordinate of the vertex using the formula y = y coordinate of focus + directrix 2. The x coordinate will be the same as the x coordinate of the focus.

(3,−1+1

    ___            

      2)

Simplify the vertex.

Add − 1 and 1. (3,0/2) Divide 0 by 2. (3,0).

Find the distance from the focus to the vertex.

The distance from the focus to the vertex and from the vertex to the directrix is | p |. Subtract the y coordinate of the vertex from the y coordinate of the focus to find p. p = − 1 − 0 Subtract 0 from − 1 . p = − 1.

Substitute in the known values for the variables into the equation ( x − h ) 2 = 4 p (y − k). (x − 3) 2 = 4 (− 1) (y − 0).

Simplify.

(x − 3) 2= −4y

= −4y
