Question

Choose the graph of the function given below.
f(x) = 2x + 3

Answer 1

Plug in values for x, solve, then graph. Do it enough times to see what graph the points form.

Answer 2

Is it R?

Answer 3

Example:
\[f(x) = 2^{x} + 3\]
\[f(2) = 2^{2} + 3\]
\[f(2) = 4 + 3\]
\[f(x) = 7\]
So you would graph (2, 7)

Answer 4

So Q?

Answer 5

I'm pretty sure it is P.

Answer 6

Ah, 2^x + 3.

When x = 0 f(x) = 1 + 3 = 4

only P has this value at x=0 (y-intercept)

Answer 7

Sorry. My original answer was for
y=2x +3 (straight line), not
y = 2^x + 3.
