Using the graph of f(x) = log10x below, approximate the value of y in the equation 10y = 6.
Log base 10 graph
y ≈ 0.01, y ≈ 1.48, y ≈ -2.01, y ≈ 0.78
Solution:
Given: Function f(x) = log10x
It can be written as
y = log10x
10y = x (Using the log formula)
Substituting the values
10y = 6
100.78 ≈ 6

Therefore, the value of y is 0.78.
Using the graph of f(x) = log10x below, approximate the value of y in the equation 10y = 6.
Summary:
Using the graph of f(x) = log10x below, the value of y in the equation 10y = 6 is 0.78.
