Answer:
b) x=1
Step-by-step explanation:
Since, graph is intersecting x-axis at (1, 0)
Therefore the equation of the graph is x = 1
You should probably post the question so that someone is able to know what you need solved
4x^2 = 100...divide both sides by 4
x^2 = 100/4
x^2 = 25....take the sqrt of both sides, eliminating the ^2
x = sqrt 25
x = 5 <===
