For the first point, remember this simple rule: every exponential function 
always returns 
when evaluated at 
. In fact, 
for every possible base .
So, we can see that the graph of the exponential passes through the point 
where 
appears to be between 1 and 2. So, the only feasible option would be 
, because it passes throught the point 
because 
.
The other functions are wrong because:
would pass through 
, which would be between 0 and 1 on the y axis
would pass through 
, which would be between 2 and 3 on the y axis
would pass through 
, which would be between 0 and 1 on the y axis
As for the second question, you simply have to plug in the values: the function
means that you have to choose an input, x, and use it as exponent for 7. So, if you choose x=2, it means that you have to give exponent 2 to 7, i.e. you replace the x with the specific value, 2.
So, the expression becomes
The answer is 3x10^12 also can i get brainliest please??
Answer:
Look at image
Step-by-step explanation:
well y-4=3(x+5)
distribute the 3 to x and 5 --> y-4 = 3x+15
now add 4 to both sides --> y-4+4 = 3x + 15 +4
y= 3x + 19
