Functions f(x) and g(x) are described as follows:
f(x) = −5x2 + 9
x g(x)
0 0
1 4
2 8
3 4
4 0
Which statement best compares the maximum value of the two functions?
It is equal for both functions.
It is 3 units higher for f(x) than g(x).
It is 3 units lower for f(x) than g(x).
It is 1 unit higher for f(x) than g(x).

Best ResponseYou've already chosen the best response.0And for g you just have to look for which g(x) value is the highest and that is the max

Best ResponseYou've already chosen the best response.0Mary wants to hang a mirror in her room. The mirror and frame must have an area of 7 square feet. The mirror is 2 feet wide and 3 feet long. Which quadratic equation can be used to determine the thickness of the frame, x? Square with an inner frame with height of 2ft on the left frame and width of 3ft on the top. Arrow on the bottom frame with an x and an arrow on the right frame with an x. x2 + 14x − 2 = 0 2x2 + 10x − 7 = 0 3x2 + 12x − 7 = 0 4x2 + 10x − 1 = 0
