Answer:
a = 7
Step-by-step explanation:
The function given is defined at x=1 as ...
f(1) = 3·1² = 3
In order to make the limit from the left be 3, we must have ...
ax -4 = 3 . . . . for x=1
1a = 7 . . . . . . .add 4
The value of the constant "a" is 7.
Answer:
y = 160 - x
Step-by-step explanation:
Given :
Maximum text character = 160
x = number of typed characters
y = Number of characters left or unused characters
Unused characters = 160 at the start of a fresh message page, which reduced as characters are being typed.
Hence,
Unused characters = (maximum characters - number of typed characters)
y = 160 - x
