Question

Rowan and Brody are both solving the equation 4x=12. Rowan is not sure what to do because he does not know a power of 4 that equals 12. Brody uses his calculator to graph y=4xand y=12 and find the point of intersection. Will Brody’s method work?

Answer 1

a

Explanation:

it was right

Answer 2

Yes, the graph intersects around (1.7925,12), so 1.7925 is a good estimate of the solution to 4x=12.
