PLEASE HELP Compare the functions show below:
Which function has the most x-intercepts?

A) f(x)
B) g(x)
C) h(x)
D) all three functions have the same number of x-intercepts.

A) f(x)

Step-by-step explanation:

f(x) has 4 x-intercepts, becoz it "cross" the x axis 4 times.

g(x) would have an infinite number of intercepts coz it is a cos function, but it gave a limit to the domain which is 0 to 2, so it only has 2 x-intercepts.

h(x) is the degree of x^3, so in theory, it has 3 x-intercepts.

x = 129

Step-by-step explanation:

Mathematically, the sum of interior angles of a polygon can be calculated using the formula;

(n-2)180

from the question given , n = 7 since the polygon has 7 sides

thus, we have it that

(7-2)180 = 5 * 180 = 900

Mathematically, by adding all the given interior angles, we can get the value of the total

We have this as;

900 = x + 131 + 119 + 125 + 133 + 125+ 138

900 = x + 771

x = 900-771

x = 129
