Be sure to include the "=" sign: <span>f(x) = 2^x -7
To find the x-intercepts, set f(x) = 0 and solve for x: 2^x - 7 = 0,
or
2^x = 7
Take the common log of both sides: x log 2 = log 7
log 7
Solve for x: x = --------- = 2.81 (approx)
log 2

Step-by-step explanation:
The first box is correct because if drawn on a praph it would show that it has a curve. Also another way to find out if it is nonlinear or linear is because the x-axis is increasing and the y-axis is decreasing. Hope this helps :)
9_>x>_-1
- x would have to be less than or equal to 9, but greater than or equal to -1. the symbols for the greater than or equal to is the > with a line under it (in case you didn’t know) and same with the less than or equal to
