Math Equations Final

Question 1

AOS

Answer 1

-b/2a

Question 2

Quadratic Formula

Answer 2

x=-b+or-square root b^2-4ac all over 2a

Question 3

Exponential Growth

Answer 3

y=a(1+r)^t

Question 4

Exponential Decay

Answer 4

y=a(1-r)^t

Question 5

Compound Interest

Answer 5

y=p(1+r/n)^nt

Question 6

Geometric Sequence

Answer 6

an=a1(r)^n-1

a1= first term
r = common ratio

Question 7

Degree of a Monomial

Answer 7

Sum of all the exponents. 0 doesn’t have a degree.

Question 8

Degree of a Polynomial

Answer 8

The greatest degree (exponent) of its terms.

Question 9

Standard Form

Answer 9

y=ax^2+bx+c

Question 10

Vertex Form

Answer 10

y=a(x-h)^2+k with vertex (h,k)

Question 11

Intercept Form

Answer 11

y=a(x-p)(x-q) - p and q are x-ints

Question 12

Transformations:

Answer 12

Parent is y=x^2
y=a(x-h)^2+k

a=vertical stretch/shrink
h=function moves left/right (opposite)
k=moves function up and down
