Answer
Explanation:
Step1: Find the domain
For the function (y = \log x), the argument of the logarithm must be positive. For (f(x)=4\log x + 3), we have (x>0). So the domain is ((0,\infty)).
Step2: Find the (y -)intercept
Set (x = 0). But (\log(0)) is undefined. So the (y -)intercept is DNE.
Step3: Find the (x -)intercept
Set (y=0), then (4\log x+3 = 0). First, subtract 3 from both sides: (4\log x=-3). Then divide by 4: (\log x=-\frac{3}{4}). Using the definition (\log x = a\Rightarrow x = 10^{a}), we get (x = 10^{-\frac{3}{4}}=\frac{1}{\sqrt[4]{10^{3}}}=\frac{1}{\sqrt[4]{1000}}\approx0.1778).
Step4: Find the asymptote
The vertical asymptote of (y = \log x) is (x = 0). For (y=4\log x+3), the vertical asymptote remains (x = 0).
Answer:
Domain: ((0,\infty)) (y -)intercept: DNE (x -)intercept: ((10^{-\frac{3}{4}},0)) (or approximately ((0.1778,0))) Asymptote: (x = 0)
