The value of A is? The value of B is?

The parabola opens: y=√x-4 (principal square root) up down right left

Write the equation in logarithmic form 8^x=64

Choose the equation below that represents the line that passes through the point (2, 4) and has a slope of 3. a) y − 4 = 3(x − 2) b) y − 2 = 3(x − 4) c) y + 4 = 3(x + 2) d) y + 2 = 3(x + 4)
