Y = b^x

when x = 1
y = b^1
y = b

Therefore, the value of b is the same as the value of y when x =1
From the graph,
When x = 1, y = 0.5
Therefore, b = 0.5

To confirm this

From the graph,

When x = -1, y = 2
Since y = b^x
2 = b^-1
2 = 1/b
2b = 1
b = 0.5

When x = -2, y = 4
Since y = b^x
4 = b^-2
4 = 1/(b^2)
b^2 = 1/4
b = √(1/4)
b = 1/2
b = 0.5

Therefore, it is conformed that b = 0.5

F(x)=x+7 if you know the domain is {-9,-3} then the range must be?

RSB [31]

Domain is the set of x-values and range is the set of images f(x).

x F(x) = x + 7

-9 -9 + 7 = -2

-8 -8 + 7 = -1

-7 -7 + 7 = 0

-6 -6 + 7 = 1

-5 -5 + 7 = 2

-4 -4 + 7 = 3

-3 -3 + 7 = 4

So the range is {-2,4} <------ answer
