Answer:
2
Step-by-step explanation:
f(x) = 2x - 3 is a linear function
The rate of change of a linear function is the measure of the slope.
The equation is in slope- intercept form, that is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 3 has slope m = 2
Thus rate of change = 2

Answer:
x=1
Step-by-step explanation:
3^ (3x+1) = 81
Rewrite 81 as a power of 3
3^4
3^ (3x+1) = 3^4
Since the bases are the same, the powers are the same
3x+1 =4
Subtract 1 from each side
3x+1-1 =4-1
3x=3
Divide by 3
3x/3 = 3/3
x =1
