The formula for exponential functions is:
y = ab^x
Answer:
B. 3x² – 10x + 13
Step-by-step explanation:
given:
f(x) = 3x² – 8x + 5
g(x) = 2x – 8
f(x) - g(x)
= (3x² – 8x + 5) - (2x – 8)
= 3x² – 8x + 5 - 2x + 8
= 3x² – 10x + 13
Since, it is given that the pentagon ABCDE is congruent to pentagon FGHIJ.
By being congruent, the corresponding angles and sides are equal.
Therefore,
,
,
,
,
.
By using 
So, 
Therefore, the measure of angle 1 is 100 degrees.
So, Option B is the correct answer.
