Question

what is the x intercept of the graph:

f(x) = 3log(x + 5) + 2

Answer 1

3log(x + 5) + 2 = 0

log(x + 5)^3 = 2

log(x + 5)^3 =2 log(10)

log(x + 5)^3 =log(100)

(x + 5)^3 =(100)

finish it offf... I got to go.

Answer 2

minor error at start
0 = 3 log(x+5) +2
3 log(x+5) = - 2 minus sign
log (x+5) = -2/3
(x+5) = 10^(-2/3)
x = 10^(-2/3) -5

etc.
