Y=35(0.35) is exponential decay
Answer:
f(-4) = 4
Step-by-step explanation:
Fro the graph attached,
We have to calculate the value of the function at x = -4.
As we can find from the graph at the input value x = -4, output value of the function is f(-4) = 4
Therefore, f(-4) = 4 will be the answer.
40x+20=1000
40x-20=1000-20
40x=980
=
x=24.5
