Answer:

-21

Step-by-step explanation:

The given functions are

f(x)=3x-4

g(x)=-2x+7

We need to find the value of (g\circ f)(6).

The substitute x=6 in f(x), to find the value f(6).

f(6)=3(6)-4=18-4=14

The substitute x=14 in g(x), to find the value g(14).

g(14)=-2(14)+7=-28+7=-21

According to the composition of functions,

(g\circ f)(x)=g(f(x))

Substitute x=6 in the above formula.

(g\circ f)(6)=g(f(6))

(g\circ f)(6)=g(14)

(g\circ f)(6)=-21

Therefore the value of (g\circ f)(6) is -21.

HELP WILL GIVE 15 POINTS <br>what is the range of this function and pls explain​
Nataly [62]

Answer:

f(x)\geq -2

Step-by-step explanation:

Range corresponds to the values of y on the y-axis. If we see the graph the minimum value of the y-coordinate is -2 and then it tends to increase from it. We do not know till where the y values will increase in the figure it shows 6 but it's still actually increasing we keep on tracing the graph but the minimum value will always remain the same which is -2 . So we can say that the range of the function is

f(x)\geq -2\\

Where f(x) is the function and since the values of y on the y-axis increase from -2 we can say that the function has the range of values greater than or equal to -2

If f(a) = 0, what is a called
diamong [38]

Answer:

A zero of the function

Step-by-step explanation:

The zeros of a function are the values of x when f(x) is equal to 0. Hence, its name. This means that when f(x) = 0, x is a zero of the function. When the graph passes through x = a, a is said to be a zero of the function.
