## Question:

Given that the graph of {eq}f(x) {/eq} passes through the point {eq}(3, 7) {/eq} and that the slope of its tangent line at {eq}(x, f(x)) {/eq} is {eq}2x + 5 {/eq}, find {eq}f(2) {/eq}.

## Tangent Line:

The equation of the tangent line to a function f(x) at a point (x0,y0) is found linearizing the function at that point, i.e

{eq}y(x) = f(x_0) + f'(x_0)(x-x_0) {/eq}

where the ' symbol denotes the first derivative operation.
