I will assume to meant that first term to be .05 a=.05 r = .1 term(7) = ar^6 = (.05) (.1)^6 = .00000005 (notice term2 had 2 zeros before the 5 term3 had 3 zeros before the 5 .. term7 has 7 zeros before the 5 ) sum(7) = (.05)(1 - .1^7)/(1 - .1) = .05555...

give the domain, range, and zeros of: f(x)=absoulte value of x-3. f(x)=x^2-4x-8 f(x)=(x+1)(x+1)(x+1). f(x)=4 f(x)=-'9x-1)^2+16 y=squareroot x. i don't understand how i konw what the range, domain, and zeros are...please give some answers so i get it

**Math**

State domain, range, period, vertical asymptotes, zeros, symmetry and y-intercept of y = -2tan(3x + 180) + 3 I just need to know if there is a formula to find the vertical asymptotes, symmetry, and zeros or do I have to solve it graphically. Thanks.
