Find the value of x where the function is discontinuous. f(x)=x^3+3^x

1 answer:

5 0

A(x)=x^3 is a polynomial function, and polynomial functions are continuous for all x,

b(x)=3^x is an exponential function, continuous for all x.

f(x)=a(x)+b(x) is continuous because the sum of 2 continuous functions is a continuous function.

Answer: f is continuous for all x in the real numbers

If the length of segment AC equals 58, what is the length of the midsegment DE

Delicious77 [7]

Answer:

B) 29

Step-by-step explanation:

Given:

AC= 58

Point D and E are the midpoints of side AB and BC Respectively.

Solution:

According to Midpoint theorem which states:

"The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side."

$\therefore$ DE= $\frac{1}{2}$ AC
