Question

Which point is on the graph of f(x)=3x5^x?

Answer 1

One point may be (2,31)
f(x)=3x5^x
f(2)=3(2)5^(2)
y=6+25
y=31
x=2

Answer 2

1. Find the y value at x=0; y=1

2. Find the y value at x=−1; y=1.6

3. Find the y value at x=-2;y=2.7

4. Find the y value at x=1; y=0.6

5. Find the y value at x=2; y=0.36

6. List the points to graph; (0,1),(−1,1.6),(−2,2.7),(1,0.6),(2,0.36)

7. Use the found points and asymptotic to graph
`y=(3^x)/(5^x)`
