Number 2 is not an equation.
Convert to vertex form:-
= -0.04(x^2 + 39x)
= -0.04( (x + 19.5)^2 - 380.25)
vertex is at -0.04 * -380.25 = 15.21 yards
Maximum height is about 15.2 yards
You would divide 23 by 9, which comes out to 2 , with a remander of 5 .so the 9 would be denominator, the 5 would be the numerator and the 2 would be you mixed number so it would be 2 5

K(x) = (1/2)ˣ
Since a (=1/2) is < 1, this exponential function is decreasing .
y-intercept for x = 0
k(x) =(1/2)⁰ → k(x) =1, then y-intercept = 1
Horizontal Asymptote:
lim k(x) = (1/2)ˣ = 0
x→∞
Horizontal asymptote x = 0
A earns $350×0.04×5 = $70 interest in interest over five years.
B earns $500×0.035×5 = $87.50 in interest over five years.
Do C the same way.
