Which function is represented by the graph?

f(x) = −2|x| + 1
f(x) =-1/2 |x| + 1
f(x) = -2|x + 1|
f(x) = -1/2 |x + 1|

i posted the problem just in case you need it.

[15 points]find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible

3x + 4y = 5 x- 3y = -7 solve by substitution

What is the sum of the geometric series in which a1 = 7, r = 3, and an = 1,701? hint: cap s sub n equals start fraction a sub one left parenthesis one minus r to the power of n end power right parenthesis over one minus r end fraction comma r ≠ 1, where a1 is the first term and r is the common ratio
