1) |x| is the absolute value function. Its vertex is at (0,0).
2) |x-1| has the same graph as does y = |x|, except that the vertex is shifted 1 unit to the left.
3) -3|x-1| has the same graph as the previous result, except that we must reflect the previous graph in the x-axis.
4) Replace the solid lines you used in this graph with dashed ones.
5) Shade the area beneath y = -3|x-1|
In summary:
the desired graph is the shaded area below the inverted v-shaped graph of
y = -3|x-1|. Its vertex is at (-1,0).
Answer:
0.75
Step-by-step explanation:
6/8 = 0.75
Or 8/6 = 1.3 repeating
F(x) = 1/2x +4
replace f(x) with y
y = 1/2x+4
switch x and y
x = 1/2y +4
solve for y
multiply both sides by 2
2x = y+8
subtract 8 from both sides
2x-8 = y
rewrite with y on the left side: y = 2x-8
replace y with f(x)^-1 (inverse notation)
f(x)^-1 = 2x-8
solve for f^-1(4)
replace x with 4 in the equation and solve:
2(4) -8 = 8-8 = 0
