Answer:

For 10-base log

x = 13.86

y = -1.52

For natural log

x = 0.63

y = -0.9

Explanation:

I'm assuming log is the 10-base logarithm here. If it's the natural logarithm, you need to redo the computations.

x intercept is the point where the chart crosses the x axis, so where y = 0

y intercept is the point where the chart crosses the y axis, so where x = 0

x intercept:

y = 0

0 = log(7x + 3) - 2

log(7x + 3) = 2

7x+3 = 10^2

7x = 97

x = 97/7 = ~13.86

y intercept:

x = 0

y = log(7*0 + 3) - 2

y = log(3) - 2

y = ~-1.52
