f (x) = -4.r – 3)+ 1 Please answer all parts: A.) What does the -4 in front tell you? (hint: it should tell you TWO things) B.) What is the vertex of this function? Explain how you know this. C.) What is the axis of symmetry? D.) What is the domain and range? ​

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b

Determine if the equation defines y as a function of x: 2xy = 1. yes o no
