Answer:
7(3x^2-6x+2)
Step-by-step explanation:
21, 42, 14 they can be divided by 7 so we put 7 out
The answer would be 400,000; 70,000; 50; 2.
Hope this helps!
Answer:
Step-by-step explanation:
From table 1,
f(x) = bˣ
For x = -1,
f(-1) = 0.5
0.5 = (b)⁻¹
b =
b = 2
For x = 1.585,
f(1.585) = 3
3 = 
3 = 


For x = 2.585,
f(2.585) = 
= 
= 4 × 1.5 [Since,
]
= 6
From table 2,
g(x) = 
For x = 0.5,
g(0.5) = -1
-1 = 
b⁻¹ = 0.5
b = 2
For x = 2,
g(2) = 1
1 = 
For x = 6,
g(6) = 2.585
2.585 = 
2.585 = 
2.585 = 
2.858 - 1 = 

For x = 3,
g(3) = 
g(3) = 1.585
To find the inverse of a function, replace every x in the equation with a y, and replace every y in the equation with an x:

Add 9 to both sides:

Square root both sides to get y by itself:

This equation can be simplified by taking the square root of 9 out of the root:


The inverse of this function is
y = 3 + √x.
