The only order pairs among the given options that represent a function is :
- (9 , -3) , (9 , -1) , (9 , -1)
Because : To be a function, every element of domain (x) can have only one unique value y, and if we get more than two values of y for same x, it isn't a function at all.
With the way the equation is written, we can assume that the “x2” is x multiplied by 2.
The x2 and 9x are like terms, and can be simplified to 11x.
Our new equation is
f(x) = 11x + 18
With no exponential functions in the equation, the difference of each value’s output would be 11.
your answer would be 17/25
C I know it’s c. I have already completed that year
Answer:
15
Step-by-step explanation:
63 - 18 = 45 ( Minus the number of cakes that are left over)
45 / 3 = 15 (Divide by 3 to find out how many cakes they sold each day)
