if g(x) is the reflection of f(x) across the x-axis that would mean g(x)= - f(x)
so that would mean you have to change all the signs of f(x) to negative
Ans: g(x)= - x^2 - 3x - 2
Desmond's times are proportional. for every 2 laps he takes 146
146 / 2 = 73
292 / 4 = 73
584 / 8 = 73
Maria's time are not proportional
150 / 2 = 75
320 / 4 = 80
580 / 6 = 96.67
5 8/9, 59/10, 5.934, 5.94 are the solutions from least to greatest.
Step-by-step explanation:

17^2 because the equation for it is a^2+b^2=c^2 so the longest side (x) is the c so 10 i put as a and 7 i put as b. it will always be squared for pythagorean theorem so the equation will look like 10^2+7^2=17^2 and if it isn’t squared all you have to do is undo the squaring
