Rewrite 3⁴ = 81 in logarithmic form.

• log₃4 = 81

• log₈₁3 = 4

• log₃81 = 4

• log₄81 = 3

Answer explanation

There is a formula for this conversion. You would use:

log_bx=y and b^y=x

What is the equation of the asymptote?

• x = -3

• x=5

• y= -3

• y=5

Answer explanation

If y=alog_b(x-h)+k.. then the asymptote will always be at x=h
