if the point (-3,4) is the vertex point of the curve of aquadratic function f and -5 is aroot of the equation f(x) =0, then what is the other root

Me find the measure to side a and the process to solve the problem you appreciate it : )

Use the graph of the sine function y=2sinθ shown below

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.
