The word "similar" from a math standpoint means to express proportionality. So long as two shapes have proportional sides, the exact lengths do not have to be equal. However, the angles need to be the same.

Using f(x)= log x, what is the x intercept of g(x)=log (x+4). use reasoning

lyudmila [28]

The x-intercept of a function is the point where it crosses the x-axis.

The x-intercept of g(x)=log(x + 4) is -3

<h3>How to determine the x-intercept</h3>

We have:

f(x) = log(x)

Rewrite as:

y = log(x)

Apply the exponent rule

$x = 10^y$

Set y to 0

$x = 1$

Given that f(x) is shifted 4 units left to get g(x).

The x-intercept of g(x) is then calculated as:

$x = 1 -4$

$x = -3$

Hence, the x-intercept of g(x)=log(x + 4) is -3
