Check all of the functions that are odd.
1 answer:
Answer:
f(x)= 4x+9
F(x)=1/x
Step-by-step explanation:
An odd function accomplish the following condition:
f(-x) = -f(x) (1)
By checking (1) on each of the next functions, we have:
f(-x) = (-x)^3 - (-x)^2 -f(x) = - (x^3- x^2)
f(-x) = (-x)^5 -3(-x)^3 + 2(-x) -f(x) = -x^5 +3x^3 +2x
f(-x)= -4x +9 = -f(x)
F(-x) = -1/x =-F(x)

Answer:
2x + 3y = 6
Step-by-step explanation:
obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y-intercept )
here m = - and c = 2
y = - x + 2 ← in slope-intercept form
multiply all terms by 3 to eliminate the fraction
3y = - 2x + 6 ( add 2x to both sides )
2x + 3y = 6 ← in standard form
Answer:
All of them are polynomials except c.
Step-by-step explanation:
Polynomials are in the form:
You can see here there are no extra symbols like square root, cube root, absolute value, and so on on the variable x...
We also don't have division by a variable. All the exponents are whole numbers.
a) While it has a square root, it is not on a variable so a is a polynomial. The exponents on the variables are whole numbers.
b) b is a polynomial also because all the exponents are whole numbers.
c) This is not a polynomial because there is a square root on a variable.
d) This is a polynomial. All the exponents are whole numbers.
