Hello, I need help on my quiz

Quiz 1.4 - TS Numerical Response 2. The y-intercept of the graph of the exponential function f(x) = 7.5(0.98) is Hint: Identify the vertical stretch factor. 6. To solve the equation 16*+4 = 64"-1, equivalent powers with base 2 could be found, and then the exponents could be equated to give the equation A. x + 4= 4x-1 B. 4x + 4 = 24x - 1 C. 4(x + 4) = 6(4x - 1) D. 8(x + 4) = 32(4x-1) Hint: Use a common base. 7. State the characteristics of the graph of the function f(x) = bm*, where b > 0 and 0 0, f(x) E R, increasing from left to right B . x > 0, f(x) E R, decreasing from left to right C. x E R, f(x) > 0, increasing from left to right D. x E R, f(x) > 0, decreasing from left to right Hint: Determine whether this is an exponential growth or decay function. Next, determine how the b-value affects the range. W
