Question

The x-intercept of the graph of f(x)=3log(x+5)+2 is:
a. 10^-2/3 - 5
b. 10^-2/3 + 5
c. 10^2/3 + 5
d. 10^2/3 - 5

Answer 1

for x - intercept put f(x) = 0 and solve for x

Answer 2

I got -5.6 for x...

Answer 3

it should be (A)

Answer 4

-4.78

Answer 5

when y=0

3log(x+5)+2=0
log(x+5)= -2/3

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

therefore, (x+5) = 10^-2/3
thus, x=10^-2/3 - 5
