Question

Match the functions to their x-intercepts.
Tiles
f(x) = log x – 1
f(x) = -(log x – 2)
f(x) = log(-x – 2)
f(x) = -log -(x – 1)

Answer 1

to find x-int , set y= 0

\[\log_{10} x - 1 = 0 \]
\[\log_{10} x = 1 \]
\[x = 10^1 = 10\]

Answer 2

thank you but i got it already

Answer 3

ok , please close thread if you no longer need help

Answer 4

i might need your help more often

Answer 5

Which exponential function does not have an x-intercept?

Answer 6

no problem, you can tag me in a question if you like

Answer 7

All exponential functions do not have x-int unless they have been shifted down
\[y = b^x - k, k > 0\]
