What is the y-intercept of the exponential function \( f(x) = 2^x \)?

La función es continua en el punto dado: \( f(x)=3 x+2 \) en el intervalo \( [0,3) \) Verdadero Falso

Sketch on the same set of axes the graphs of \( f(x)=-2 x^{2}-4 x+6 \) and \( g(x)=-2 \cdot 2^{x-1}+1 \) Clearly indicate all intercepts with the axes, turning point(s) and asymptote(s).

What effect does multiplying the function \( f(x) = 3^x \) by -1 have on its graph? Describe any transformations.
