The set of rational plus irrational numbers equals ALL REAL NUMBERS

Yes, it is a function because every x-value maps into only one y-value. In other words, because rational and irrational are mutually exclusive, x does not map into both 0 and 1

Domain is all real numbers.

Range is 0 or 1

y-intercept happens when x=0, so that is a rational number and y = 1

There are an infinite number of x-intercepts. Every irrational number is an x-intercept

Neither even or odd because it is not symmetric with either the y-axis or the origin.

The graph jumps between y=0 and y=1

Hope that helps Answer:

Answer:

$\log_{10}(147) = 2.1673$

Step-by-step explanation:

Given

$\log_{10} 3 = 0.4771$

$\log_{10} 5 = 0.6990$

$\log_{10} 7= 0.8451$

$\log_{10} 11 = 1.0414$

Required

Evaluate $\log_{10}(147)$

Expand

$\log_{10}(147) = \log_{10}(49 * 3)$

Further expand

$\log_{10}(147) = \log_{10}(7 * 7 * 3)$

Apply product rule of logarithm

$\log_{10}(147) = \log_{10}(7) + \log_{10}(7) + \log_{10}(3)$

Substitute values for log(7) and log(3)

$\log_{10}(147) = 0.8451 + 0.8451 + 0.4771$

$\log_{10}(147) = 2.1673$
