Given the function f(x)=-x+3, find the value of f(13).

Answers

Answer 1

F(13) means x equals 13.

Replace x in the equation with 13 and solve:

-13 + 3 = -10

F(13) = -10

Answer 2

Answer:

-10

Step-by-step explanation:

if the x in f(x) is 13, then the x in the equation is 13 and there is a negative sign in front so it is negative 13 plus 3 which is negative 10

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The question is incomplete.

Please refer to the picture for the complete question.

We have:

A t-shirt increased in price by 1/4. After the increase, it was priced at £65.

Let's suppose the original price was x

(1 + 1/4)x = 65

(1 + 0.25)x = 65

1.25x = 65

x = £52

Thus, the original price was £52 if the t-shirt increased in price by 1/4. After the increase, it was priced at £65.

k = 1/2

Step-by-step explanation:

g(x) = 3 - kx   g^-1(4) = -2

y = 3 - kx

x = 3 - ky

x - 3 = -ky

(x-3) / (-k) = y

(x-3) / (-k) = (g^-1(x))

4-3 / (-k) = -2

1 / (-k) = -2

1/k = 2

1 = 2k
