Domain is the set of values of x.
Notice that in the graph x start from origin x=0 and goes till x=4 which shows x is from 0 to 4.
Hence the domain of the function is 0<x≤4.
Similarly y starts from origin and stop at y=40.
So, range is 0<y≤40.
Answer:
17
Step-by-step explanation:
Substitute.
f(x)=3(5)+2
=15+2
=17

Answer:
y = 4 · ½ˣ
Step-by-step explanation:
It passes through the point (0, 4), so:
4 = a · b⁰
a = 4
It passes through the point (2, 1), so:
1 = 4 · b²
1/4 = b²
b = ½
y = 4 · ½ˣ
