What is the domain of the function represented by the graph?
ioda

Answer:

c

Step-by-step explanation:

because mathematically 0 less than or equal to x less than or equal to 4 means starting from 0 up to 4 is the domain of the graph

but if we were asked about the range it was going to be all real number (B) because if the range means the value of y then y have solution in all the way down

For the polynomial 6xy2 – 5x2y? + 9x2 to be a trinomial with a degree of 3 after it has been fully simplified, the missing expon
Karolina [17]

Consider the polynomial 6xy^2-5x^2y^?+9x^2.

For this polynomial to be trinomial with a degree of 3. We have to identify the missing exponent of the 'y' term.

Let the missing exponent of the 'y' term be 0

So, the polynomial will be 6xy^2-5x^2y^0+9x^2

= 6xy^2-5x^2+9x^2

= 6xy^2+4x^2 which is not a trinomial, which is a binomial.

So, the missing exponent of 'y' can'not be zero.

Let the missing exponent of the 'y' term be 2

So, the polynomial will be 6xy^2-5x^2y^2+9x^2

= 6xy^2-5x^2y^2+9x^2

= 6xy^2-5x^2y^2+9x^2 which is a trinomial of degree 4.

So, the missing exponent of 'y' can'not be '2'.

If we will take the missing exponent of 'y' more than 2, than the degree of the given polynomial will not be 3 anymore.

Let the missing exponent of the 'y' term be 1

So, the polynomial will be 6xy^2-5x^2y^1+9x^2

= 6xy^2-5x^2y+9x^2

= 6xy^2+4x^2 which is a trinomial of degree 3

So, the missing exponent of 'y' is 1.

What is the quadratic equation to this question
-BARSIC- [3]

Answer:

f(x) = 4x − 12

Step-by-step explanation:

It's not quadratic.  It's linear.  Each time x increases by 1, f(x) increases by 4.  So the slope is 4.  The y-intercept (when x=0) is -12.  The equation of the line is therefore:

f(x) = 4x − 12
