we are given
piecewise function as
f(x) =5 when x<=-2
f(x)=ax+b when -2<x<3
f(x)=-5 when x>=3
We are given f(x) is continuous for all values of x
so, it will also be continuous at x=-2 and x=3
Continuity at x=-2:
Value of both functions must be same at x=-2
so, we get
Continuity at x=3:
Value of both functions must be same at x=3
so, we get
so, we get system of equation as
now, we can subtract both equations
and we get
now, we can find b
so, we get

Answer:
x = 5^(2/3)
Step-by-step explanation:
x^3 = 25
Rewriting 25 as 5^2
x^3 = 5^2
Take the cube root of each side
x^3 ^ 1/3 = 5^2 ^ 1/3
x = 5^(2/3)
9x^2 - 12y^2 - 11x, the last answer, number 4
It's being divided by 3 each time. So, the next 2 are: 1.2 and 0.4.
Answer:
n=-19
Step-by-step explanation:
You have to multiply each side by -2. This cancels out the division. Then you subtract 3 from both sides. Then you get the answer. Hope this helps!
