A 2-column table with 6 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2, 3. The second column is labeled f of x with entries 20, 0, negative 6, negative 4, 0, 0. Which is an x-intercept of the continuous function in the table?

(–1, 0)
(0, –6)
(–6, 0)
(0, –1)

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

48+y= ?

the y is the variable and the ? could also be a variable  

i'll be glad to : )
