Y = 7.75x
when x = 4 we have
y = 7.75 * 4 = 31 dollars answer
Y1=2/3x , Y2=2/3x-2
those are the graph of the functions
Step-by-step explanation:
Standard form of a quadratic is f(x) = ax² + bx + c.
To convert to vertex form, the simplest method is to find the x-coordinate of the vertex using h = -b/(2a).
Then, plug back into the equation to find the y-coordinate of the vertex. k = f(h).
Finally, the leading coefficient is the same as the standard form, a.
f(x) = a(x − h)² + k
Another method is to complete the square.
