Answer:
f(x) = 30(0.7746)^x
Step-by-step explanation:
30 (y)^0 = 30
30(y)^2 = 18 We need to find the value of y.
y^2 = 18/30 = 0.6
y = sqrt0.6 = 0.7746
so the exponential function is 30(0.7746)^x
Here we MUST follow Order of Operations rules.
Must start out by doing the work inside the parentheses: (8+7) = 15
Next, multiply this result by 3: 3(15)=45 (answer)
You will have to work out the given versions of this problem until you find one that is also equal to 45.
1. x=7
2. x= -6
