Exponential Functions

With exponential i understood with graph and tables but i had trouble with finding them with word problems and I continuously need to work on not gettin tricked by words and also pointing out spefic words used to help me find my answer for future text and quizzies etc.

Forms

Standard form: y=ax^2+bx+c

Vertex form: a(x-h)^2+k

Factored form: (x-p)(x-q)

Determining the Number of Solutions

• looking value of the discriminant

• discrimiant is 0, then its 1 solution

• discrimiant is negative, then its no solution

• discrimiant is positive, then it 2 solutions

discriminat= b^2-4ac
