Question

Compare the graphs below of the logarithmic functions. Write the equation to represent g(x).

a graph of f of x equals log x and a graph of a similar log function, g of x, that is the same as f of x and shifted up 4 units

g(x) = log(x) − 4
g(x) = log(x) + 4
g(x) = log(x + 4)
g(x) = log(x − 4)

Answer 1

its either D or A i believe

Answer 2

i like explantions

Answer 3

The answer would be, B, g(x) = log(x) + 4

Reasoning:
\[g(x)=f(x)+4\]

So if we put 1 into where x is then we would get
\[f(1)=\log(1)=0\]
\[g(1)=\log(1)+4=4\]

So this means it is B, g(x) = log(x) + 4
