Which graph represents an exponential function? answer fast im timed

Exponential graphs are increasing or decreasing graphs: as the value of x increases, the value of f(x) also increases Or as the value of x decreases , the value of f(x) also decreases.

1) The first graph is a Parabola .It represent a quadratic function.

2)The second graph is also an inverted parabola and represents a quadratic function.

3) The third graph is representing a Hyperbola.

4) The graph is representing a radical function.

5) The graph is representing an exponential function.

The last graph represent an exponential function.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
