The function has a domain of all real numbers . True
<em>The cube root of real number is also real. The negative sign is outside he radical so it cannot result to an imaginary number.</em>
The function is a reflection of y =³√x . True
The function is always increasing. False
<em>When getting the cube root of a number the result is alway smaller. So the domain of the function should be decreasing not increasing.</em>
The function has a range of {y|– < y < } . False
The function passes through the point (3, –27) . False
<em>When this values are substituted it the function they don't satisfy it. </em>
Answer:
#1 - a mathematical relationship or rule expressed in symbols which help you solve something
#2 - variables, which represent an aspect of the problem
#3 P is perimeter, L is length, W is width, A is area
#4 Because in order to find the perimeter, you need to multiply the length and the width twice then add them.

Step-by-step explanation:
<h3>1.</h3>
Solid dots go at all the end points except the one at (3, 6), which gets an open dot signifying the function is not defined for that point.
For the first portion of the graph, the square root function is shifted left one unit and scaled vertically by a factor of 3.
The second portion of the graph is a line with a slope of -1. It would have a y-intercept of 5 if it were defined there. It has an x-intercept of 5.
<h3>2.</h3>
The y-intercept is found by setting x=0 and solving for y.
... y = log(2·0+1) -1 = log(1) -1 = 0 -1 = -1
The x-intercept is found by setting y=0 and solving for x.
... 0 = log(2x +1) -1
... 1 = log(2x +1) . . . add 1
... 10 = 2x +1 . . . . . . take the antilog
... x = (10 -1)/2 = 4.5 . . . . . subtract 1, divide by the x coefficient
The intercepts are (0, -1) and (4.5, 0).
Answer:
-9.5
Step-by-step explanation:
-4.75 = z/2
(2)-4.75 = (z/2) * (2)
-9.5 = z
Answer:
$28360
Step-by-step explanation:
Step one:
Given data
P=20000
rate= 6%
time= 6years
Step two:
compound interest
A=P(1+r)^t
substitute
A=20000(1+0.06)^6
A=20000(1.06)^6
A=20000*1.418
A=$28360
