Question

Select the possible locations for the graph of (x, y), in terms of axes, given the condition xy = 0
a.
x- axis
c.
origin
b.
y- axis
d.
all of these

Answer 1

the answer is all of these. is xy = 0, then one of them have to be 0. but, there also can be multiple answers:
like x = 5 and y = 0, 5(0) = 0, but x is at 5, on the x axis.

same for y, y = 5 and x = 0, (0)5 = 0, but y is on 5.

if both are 0, then (0)0 = 0

so all 3 are correct.

Answer 2

For the function describe the domain and range.
f(x)=x^2

a.domain: all imaginary numbers
range: all negative numbers
c.domain: all real numbers
range: all non negative numbers

b.domain: all imaginary numbers
range: all non-negative numbers
d.domain: all real numbers
range: all negative numbers

Answer 3

for f(x) = x^2, the answer is D. it can answer all real numbers and all negitive numbers.

Answer 4

sorry, domain: all real #'s, range: all negitive numbers

Answer 5

Graph the following functions,f(x)=x^2,g(x)=1/2x^2 , and identify the transformation from f to g.

a.horizontal compression
c.horizontal stretch
b.vertical stretch
d.vertical compression

Answer 6

vertical compression. g(x) graph is wide, but when you square it by putting G(x) into f(x) equation, it vertical compresses it.

Answer 7

Write a direct variation equation that relates x and y. Assume that y varies directly as x. Then solve.

If y = –5 when x = 25, find x when y = 45

Answer 8

The length of the sides of four triangles are given. Determine which triangle is not a right triangle.
a.
5 mm, 12 mm, 13 mm
b.
20 mm, 48 mm, 52 mm
c.
6 mm, 8 mm, 10 mm
d.
11 mm, 24 mm, 26 mm

Answer 9

@SauceBoss72

Answer 10

for the direct variation equation is 1/5th of a difference, so x is equal to 9

Answer 11

for your second question, the answer is D. all of the first 3 are right triangles if you use the pythagorean therom

Answer 12

How many $5 movie tickets can you buy with $37?
a.
7
c.
6
b.
8
d.
9 @SauceBoss72

Answer 13

the answer is A, 7. just do 37 - 5 until you cant do it anymore. youll get 2 when you subtract 7 times, or just do 7 x 5 = 35 37-35 = 2

Answer 14

Given F(x)=x^20-1 , write an ordered pair (x, y) for the following elements of the domain. x = 0
a.
(1, -1)
c.
(0, -1)
b.
(0, 1)
d.
(0, 0)

Answer 15

@SauceBoss72

Answer 16

domain is (1, -1)

Answer 17

Which of the following transformations have been applied to the graph of the parent function,y=x^2, to produce the graph of the function y=0.4(x+2)^2+5
a.
horizontal translation of -2, vertical translation of 5, vertical compression by a factor of 0.4
b.
reflection across the x-axis, horizontal translation of -2, vertical translation of 5, vertical stretch by a factor of 4
c.
horizontal translation of 2, vertical translation of -5, vertical compression by a factor of 0.4
d.
reflection across the x-axis, horizontal translation of -2, vertical translation of -5, vertical stretch by a factor of 4
