PLZ HELP, DUE TONIGHT!! Find the values of a and b such that f(x) is continuous at x=1

Sedaia [141]

Answer:

a = 2, b = -4

Step-by-step explanation:

To make the given piecewise function continuous we need:

ax² - b = 6 and 5ax + b = 6 at x = 1

It gives us the system:

a(1²) - b = 6 ⇒ a - b = 6
5a(1) + b = 6 ⇒ 5a + b = 6

Sum of the two:

a - b + 5a + b = 6 + 6
6a = 12
a = 2

Then b is:

2 - b = 6
b = -4

I need to know how to simplify this equation

ArbitrLikvidat [17]

$\frac{ {3}^{x + 4} - {3}^{2x + 2} }{ {3}^{x - 2} \times {3}^{x + 4} } = \frac{x + 4 - 2x - 2}{(x - 2) \times (x + 4)} = \frac{ - x + 2}{ {x}^{2} + 4x - 2x - 8 } = \frac{ - x + 2}{ {x}^{2} + 2x - 8}$
i could be wrong, was kinda in a rush
