Express the function in the form f(x) = a(x - h)2 + k and indicate the vertex.f(x) = x2 + 14x + 1
A. f(x) = (x - 7)2 + 148 vertex: (7, 148) B. f(x) = (x - 14)2 + 393 vertex: (14, 393) C. f(x) = (x + 7)2 - 48 vertex: (-7, -48) D. f(x) = (x + 7)2 - 146 vertex: (-7, -146)
Solve the problem.A vendor has learned that, by pricing pretzels at $1.00, sales will reach 159 pretzels per day. Raising the price to $2.00 will cause the sales to fall to 119 pretzels per day. Let y be the number of pretzels the vendor sells at x dollars each. Write a linear equation that models the number of pretzels sold per day when the price is x dollars each.
A. y = -40x + 199
B. y = - 
x + 
C. y = -40x - 199
D. y = 40x + 119
