Answer:
f(0)=4
Step-by-step explanation:
f(0)=4*9^0=4*1=4
Answer:
72.5
Step-by-step explanation:
General equation of parabola
for vertex(h,k)
Now
So
equation of parabola
D = (5-1)/(13-(-3)) = 0.25
f(13) = 13d + x = 13 * 0.25 + a = 3.25 + a = 5
a = 1.75
f(x) = 1.75 + 0.25x
A triple number has 3 numbers and a double numbers has 2 numbers only.
