F(x)= 8(b)^x
f(1)=8(b)^1
4/8=b
1/2=b
f(1)=4
a is initial value/ y intercept which is 8.
f(x)=8(1/2)^x
Answer:
a) Slope: -2
b) y=2/5x+2
C) x=2.5
D) y=-7x-2
Step-by-step explanation:
I don't want to type all my work but that's what i got
f(x) = 2(5)ˣ
You can tell from the given equation that (5) is the multiplicative rate of change because 5 is the value being raised to the x-power.
Let's see if that is true:
x y
1 10 (10 x 5 = 50) so next y-value should be 50.
2 50 (50 x 5 = 250) so next y-value should be 250.
3 250
Can you calculate what the next ccordinate will be? (4, ____) <em>(250 x 5 = 1250)</em>
Answer: 5
Answer:
i think it is b but I can be wrong
