Which is a stretch of an exponential decay function? O fx) = 4/5(5/4)x
o f(x) =4/5(4/5)x
O f(x) =5/4(4/5)x
O f(x) = 5/4(5/4)x

Which equation represents a direct linear variationa. y=x2b. y=2/5xc. y=1/xd. y=x+3

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)

If f(x)=x/2-3 and g(x)=4x^2+x-4, find (f+g)(x)
