2. When solving a quadratic equation by graphing, we find the roots using which of the following?
Vertex
O y-intercepts
O z-intercepts
None of the above

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

26- 6 = 20. erica has 20 bottles left

continuous functions:

a function is said to be continuous , if it is an increasing function or decreasing function or both increasing and decreasing function.

if function is increasing continuous function

then for,

if function is decreasing continuous function

then for,

so , in the situation described,for which functions will the y-values be the greatest for every large values of x describes continuous increasing function.as i have defined continuous increasing function

the function having larger slope, will have larger y values , for larger values of   x .

slope between two points (a,b) and (p,q) is given by :

m=

slope in option 1 =75

slope in option 2 =5

slope in option 3 = 200

as the fourth option is a geometric progression, common ratio being 3. as x value increases by 1 , y value increases 3 times.the function can be written as: y=7. [n=0,1,2,3]

option (3) and option (4) is right choice.in each case y value increases with increase in value of x.
