Which of the following functions are written using function notation? g(x) = 5x + 2 y = 1 x h = x2 r(x) = x f/x = x5 - 3 b(x) = 1 2 x3 p/x = -7x k(x) = - 3 x + 1 y = mx + b fx = -x3 + 4

We are given : g(x) = 5x + 2.

y = 1 x

h = x^2

r(x) = x

f/x = x^5 - 3

b(x) = 1/2 x^3

p/x = -7x

k(x) = - 3 x + 1

y = mx + b

fx = -x^3 + 4

Note: Function is written in the from of f(x) and read as function f of x.

There could be any letter used for function, like h(x), g(x), k(x).

Therefore, in the given options the following are in function notations only:

g(x) = 5x + 2.

r(x) = x

b(x) = 1/2 x^3

k(x) = - 3 x + 1.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
