Can someone help me pls

What is the y-intercept of the graph of the equation y=3(2^x)

Ily begins solving the equation 4(x – 1) – x = 3(x + 5) – 11. her work is shown below. 4(x – 1) – x = 3(x + 5) – 11 4x – 4 – x = 3x + 15 – 11 3x – 4 = 3x + 4 how can her partial solution be interpreted?

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2
