Step-by-step explanation:
Answer:
To make a table u need to have coordinates, (x, y).
Solve for them using substitution:
y = x - 4 ↔ x = y + 4
y = (2x - 17)
PLUG IN TO y = (2x - 17).
y = (2(y+4) - 17)
Solve for y:
y = 2y + 8 - 17
y = 2y - 9
-1y = -9
y = 9
Solve for x:
x = (9) + 4
x = 13
Keep solving for x and y to have your coordinates for your table.
Answer:
Step-by-step explanation:
a1=7
a2=13
c.d. d=13-7=6
an=a1+(n-1)d
an=7+(n-1)6=7+6n-6=6n-1
recursive formula
c.d .=an-a(n-1)
6=a_{n}-a_{n-1}
a_{n}=a_{n-1}+6
Answer:3

A: f(x)=8x-2
1. Switch the f(x) to y
y=8x-2
2. Switch y to x and x to y
x=8y-2
3. Solve for y:
------------------------------
1. Add 2 to both sides.
x=8y-2
+2 +2
2. Divide both sides by 8.
x+2=8y
--- ---
8 8
1/8x+1/4=y
3. Write in f-inverse form
f^-1(x)=1/8x+1/4
B: g(x)=2/3x+6
1. Switch the g(x) to y
y=2/3x+6
2. Switch y to x and x to y
x=2/3y+6
3. Solve for y:
------------------------------
1. Subtract 6 from both sides.
x=2/3y+6
-6 -6
2. Multiply both sides by 3/2 (to cancel out the 2/3)
x-6=2/3y
2/3x-4=y
3. Write in f-inverse form
g^1(x)=2/3x-4
C: h(x)-4x-12
1. Switch the h(x) to y
y=-4x-12
2. Switch y to x and x to y
x=-4y-12
3. Solve for y:
------------------------------
1. Add 12 to both sides.
x=-4y-12
+12 +12
2. Divide both sides by -4
x+12=-4y
------ ---
-4 -4
-1/4x-3=y
3. Write in h-inverse form
h^2(x)=-1/4/x-3
