Question

Please help me out with this!

Answer 1

f(x)=5(2^x)

f(0)=5(2^0)

f(0)=5(1) note any number n^0=1

f(0)=5

Answer 2

Simple, plug in 0. When X is 0, we have our y-intercept. Remember, X=0


`f(x) = 5( {2}^(x) ) \\ f(0) = 5( {2}^((0)) ) \\ f(0) = 5 \\ (0,5)`
Our y-intercept is 5. X=0, Y=5 hence (0,5)
