Answer:

jenny

Step-by-step explanation:

Jenny is correct because a function is a set of inputs to a set of possible outputs and a big rule of a function is that the x values can not repeat. The y values are allowed to repeat but not the x values and in c there are 2 values of 2 causing it to not be a function. (:

The number of tomato plants Jeff planted went from 4 last year to 12 this year. Find the percent increase.​
Dafna1 [17]
200%

We find the difference, then divide that by the original. 12-4/4 = 8/4 = 2
Multiply by 100 to get the percentage, = 200%

Also, adding 4 would be a 100% increase, and adding 8 is twice that, so 200%.

Do rational expressions contain logarithmic functions? A. always B. sometimes C. never
bazaltina [42]

The right answer is C. never


The quotient of two algebraic expressions is a<em> fractional expression. </em> Moreover, the quotient of two <em>polynomials</em> such as:


\frac{1}{x} \\ \\ \frac{3x-2}{1+x} \\ \\ \frac{x^2-4}{x^2+2}


is called a rational expression. So according to this definition rational expressions does not contain logarithmic functions. In fact, a rational expression is an expression that is the ratio of two polynomials like this:


f(x)=\frac{P(x)}{Q(x)} \\ \\ with \ Q(x) \neq 0
