If y varies directly as x, and y=14 when x=3.5 find y when x=2

y varies directly as x

y ∞ x

y=14 when x=3.5

y = kx

k is a constant, when multiplied by x, you get y

14 = 3.5k

Solve to find k:

14/3.5 = k

14/3.5 = 4

k = 4

y = 4x

Find y when x=2

y = 4x

y = 4(2)

you can not solvr this without numbers

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
