Answer

$y = 6x + 1$

Work Step by Step

1. Find the derivative of $f(x)$ $f(x) = e^{6x}$ $f'(x) = 6e^{6x}$ 2. Substitute the point (0, 1) into $f'(x)$ to find the gradient of the tangent $f'(0) = 6e^{6(0)}$ $=6e^{0}$ $m =6$ 3. Substitute the coordinates and the slope into the equation of the line $y = mx + b$ $1 = 6(0) + b$ $1 = 0 + b$ $b = 1$ 4. Write the equation of the tangent $y = 6x + 1$
