What is the approximate value of x in the equation below? log5(15)=x+3 –2.523 –1.317 2.880 7.485

Option B is correct.

The value of x is -1.371(approximate)

Explanation:

Given equation: =x+3

Using logarithmic rule:

We can write as;

                [using logarithmic rule]

By graphing calculator the value of = 0.682606194486.

then, we have

substitute this value in [1] to solve for x;

Subtract 3 from both sides we have,

Simplify:

-1.31739381 =x or

x =-1.317 (approx.)

Therefore, the approximate value of x is : -1.317

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
