Answer:
0.015625
Step-by-step explanation:
the answer is 0.015625
She didn’t notice that the 3 and the 4 both do not have the variable “n” with them
She just added up all the numbers together then added the variable at the end.
A) f(x) = 2 - 2x
f(0) = 2 - 2(0) = 2 - 0 = 2
f(2) = 2 - 2(2) = 2 - 4 = -2
f (4) = 2 - 2(4) = 2 - 8 = -6
b)
___________
| y = 2x - 5 | y |
________ |__
-2 | -9
-1 | -7
0 | -5
1 | -3
2 | -1
Answer:
To find the inverse, interchange the variables and solve for
y
.
f
^−
1
(
x
) = −
9 − x − √
(x
^2 − 18
x + 201
)) /(12
) ,
(−
9 − x + √
(x
^2 − 18
x + 201)) / (12
)
To do this you want to first add 9 1/2 to 62 1/4. 9 1/2 is changed to 9 2/4. 9 2/4 plus 62 1/4 is 71 3/4. Now you have to add 2/14 to 71 3/4 to find how tall their father is. 2/14 plus 71 3/4 is 74. Their dad is 74 inches tall which is equal to 6 feet 2 inches.
