The graph of quadratic function f(x) has a minimum at (-2,-3) and passes through the point (2,13). the function g(x) is represented by the equation
g(x) = -(x+2)(x-3).

how much greater is the y-intercept of g(x) than f(x)?

ANSWER

The y-intercept of g(x) is 5 greater than f(x)?

EXPLANATION
The function f(x) has a minimum at (-2,-3) and passes through (2,13).
The equation in vertex form is given by,





We substitute (2,13) to find the value of a,











The y-intercept is



Also,



has y-intercept,



The difference is

You would plot 83 on the 83 line and you would plot -113 on the -113 line.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
