The function f(x) is a polynomial, while the function g(x) is a logarithmic function and the functions have the same range
<h3>The type of functions</h3>
The functions are given as:
f(x) = x³ + x² - 2x + 3
g(x) = log(x) + 2
The function f(x) is a polynomial, while the function g(x) is a logarithmic function.
<h3>The key features</h3>
For the polynomial function, we have:
- Domain: -∞ < x < ∞
- Range: -∞ < x < ∞
- y-intercept = 3
For the logarithmic function, we have:
- Domain: x > 0
- Range: -∞ < x < ∞
- y-intercept = undefined
By comparison, the functions have the same range

Answer:
a) 22.6
b) 23
Step-by-step explanation:
a)
Step 1: 18 + 9 + 7 + 35 + 30 + 21 + 33 + 12 + 30 + 31 = 226
Step 2: 226/10 = 22.6
b)
Step 1: 226+27 = 253
Step 2: 253/11 = 23
Answer:
15
Step-by-step explanation:
Answer:
x=40 and y= 60
Step-by-step explanation:
<u>step:1</u>
Let 'x' and 'y' are two numbers
given data the sum of two numbers is 100
x+y = 100......(1)
Given difference of two numbers are
x - y = -20 ......(2)
<u>Step :2</u>
solving the equation (1) and (2)
adding the equations (1) and (2)
x+y+x-y=100-20
cancelling 'y' terms are
2 x = 80
dividing "2" on both sides, we get
x = 40
<u>Step :3</u>
substitute x = 40 in equation (1)
x + y =100
40 + y = 100
subtracting "40" on both sides, we get
40 + y - 40 = 100 -40
y = 60
Final answer:-
The two numbers are x = 40 and y= 60
Step-by-step explanation:
1/2(4-14y)=y+50
1/(8 - 28y) = y + 50
8y - 400 - 28y² +
Now you can solve
