1) is the relation xy=5 a function within the domain(-5,-1)

2)f(x)=4x^2-2x-6 and g(x)=2x-3 find the domain of (f-g)(x) and (f/g)(x)

3)find two numbers Y such that the distance from (-3,2)to (5,Y)is 10

4)Parallel to the line 2x-3y+4=0 passing through the origin

5)slope passing through the points (5,4)

6)A line passing through the points (7,-3)and(1,3).find standard form of the line and the linear function define by f(x)=mx+b that has the line as its graph. Answer by stanbon(75887) (Show Source):

You can put this solution on YOUR website! 1) is the relation xy=5 a function within the domain(-5,-1)

Ans: yes

———————————————

2)f(x)=4x^2-2x-6 and g(x)=2x-3 find the domain of (f-g)(x) and (f/g)(x)

(f-g)(x+ – f(x)-g(x) = 4x^2-3

Domain: All Real Numbers

—————

(f/g)(x) = (4x^2-2x-6)/(2x-3)

Domain: All Real Numbers except x = 3/2

—————-

3)find two numbers Y such that the distance from (-3,2)to (5,Y)is 10

(y-2)^2 + (5–3)^2 = 10^2

(y-2)^2 + 64 = 100

(y-2)^2 = 36

y-2 = 6 or y-2 = -6

y = 8 or y = -4

——————–

4)Parallel to the line 2x-3y+4=0 passing through the origin

slope = (2/3)

EQUATIOn: y = (2/3)x

———————-

5)slope passing through the points (5,4)

4/5

————

6)A line passing through the points (7,-3)and(1,3).find standard form of the line and the linear function define by f(x)=mx+b that has the line as its graph.

slope = 6/6 = 1

interdept: 3 = 1 + b

b = 2

EQUATION:

y = x + 2
