Pls help me

Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit.

Select all that apply.

(f(x) = 86-8)
19(x) = log(3x)+2

Pls Help Me Use Technology To Approximate The Solutions To The System Of Equations To The Nearest Tenth Of A Unit Select All That Apply Fx 868 19x Log3x2 class=

2 Answers: Choice D and Choice E

Explanation:

I used GeoGebra to determine that the approximate solutions in (x,y) form are

(0.00333, 0)

(9.59682, 3.45925)

These are the locations where the two graphs cross or intersect.

When rounding to the nearest tenth, we end up with (0, 0) and (9.6, 3.5) which is why the answers are D and E.

Be careful to keep in mind that x = 0 is not in the domain of g(x) since log(0) is undefined. So it's fairly misleading to say that (0,0) is an intersection point when it's not even on the graph of g(x). This is one big issue with rounding numbers that we lose crucial information like this.
