Question

Karim graphs the function f(x) = 2x - 4. Hewants to determine the point wherek(x) = x + 3 intersects f(x).At which point will Karim find thatf(x) = k(x)?

Answer 1

f(x) = 2x - 4

Then find

k(x) = f(x)

Now replace

x+ 3 = 2x -4

Solve for x

x + -2x = -4 - 3

. -x = -7

. x = 7

Now find y = f(x) = k(x)
