What role does the coefficient 'c' play in an exponential equation?

• It changes the direction of the curve.

• It shifts the graph up or down, affecting the horizontal asymptote.

• It affects the x-intercept of the graph.

What was the initial model used to predict COVID-19 cases in Canada?

• N(t) = 0.74e^(0.2t) + 4.5

• N(t) = 0.74e^(0.2t - 23) + 4.5

• N(t) = 0.74t^(0.2) + 4.5

• N(t) = e^(0.74t) + 4.5

Why are exponential models not always realistic for long-term predictions?

• They can predict more cases than the actual population.

• They always underestimate the number of cases.

• They cannot account for changes in variables.

• They are only accurate for physical phenomena.

• Population growth

• Cooling of a liquid

• Radioactive decay

• Determining the area of a circle
