Question

Select all the correct graphs.
Choose the graphs that indicate equations with no solution.

Answer 1

Graph 1 and Graph 5

Explanation:

As the first and final graphs do not intersect at any points on their graphs, they have no solution.

Answer 2

-2x - 1 = 3^(-x); 2^(-x) + 2 = -5^x + 3

Explanation:

for this question you are choosing the lines that do not touch

the graphs for the second third and fourth ones all touch

but

the first and last one do not

therefore those are the ones with no solution
