Explain how to solve 4^x+3 = 7 using the change of base formula log base b of y equals log y over log b. Include the solution for x in your answer. Round your answer to the nearest thousandth.

The value of x is 1

Explanation:

The equation is

Subtracting both sides by 3, we get,

Taking log on both sides, we get,

Rewriting the equation by

Thus, we have,

Applying log rule, if , then

Thus,

Substituting in , we get,

Also, since, , then

Thus,

Hence, the value of x is 1

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
