Hey user☺☺
Option a is correct
Because the graph has only one solution.
As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.
Hope this will help☺☺

Answer:
The relation for the distance cover by Tina and Lia is 20 = 4 × m
Option B
Step-by-step explanation
Given as :
The distance cover by Tina = 
= 20 miles
The distance cover by Lia = 
= m miles
According to question
Tina walked 4 times as far as Lia
So, The distance cover by Tina = 4 × The distance cover by Lia
Or, = 4 ×
I.e 20 miles = 4 × m miles
or. 20 = 4 × m
So, relation is 20 = 4 × m
Hence, The relation for the distance cover by Tina and Lia is 20 = 4 × m
I.e option B Answer
