An arithmetic sequence has this recursive formula:
(a1 = 5
(a^n. = a^n-1 - 4
what is the explicit formula for this sequence?

a. a^n=(-4)+(n-1)5
b. a^n=5+(n-)
c. a^n=5+(n-)
d. a^n=(-1)+(n-)

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
