Step-by-step explanation:</h2>
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

i would pick a or d sorry i cant help Step-by-step explanation:
Answer:
<h2>Answer : (4,0)</h2>
<h2>If x = 4 and y =0 then putting the values in the equation we get —</h2>
<h3>2 × 4 - 0 = 8 - 0 =8</h3>
<h2>We can use another pair that is (5,2)</h2>
<h2> By putting the values in the equation we get, </h2>
<h3>2 × 5 -2 = 10-2 =8</h3>
<h2>So (5,2) and (4,0) are the solutions of the equation. </h2>
So

The standard form of an equation of a line is y=mx+b. Our example equation will be 15=5x+3. The y-intercept would be when x=0, and the slope is m. We need to use algebra to find the y-int, but we can find the slope with just the equation. m=5.
To find the y-int, we need to set x as zero. This is because the intercept will be on an axis, therefore x is zero.
15=5(0)+3
15=0+3
15=3
y=3
The y-intercept is 3. The slope is 5.
