Answer:
Which design do you prefer
Step-by-step explanation:
4 x^2 + 20 x + 25 = 7
Divide both sides by 4:
x^2 + 5 x + 25/4 = 7/4
Write the left-hand side as a square:
(x + 5/2)^2 = 7/4
Take the square root of both sides:
x + 5/2 = sqrt(7)/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
x = sqrt(7)/2 - 5/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
Answer: x = sqrt(7)/2 - 5/2 or x = -5/2 - sqrt(7)/2
The true regarding the functions on the graph is f(2) = g(2)
<h3>How to determine the true statement?</h3>
The graph that completes the question is added as an attachment
From the attached graph, we can see that both lines intersect at:
x = 2
This means that:
f(2) = g(2)
Hence, the true regarding the functions on the graph is f(2) = g(2)
