Q. The function m m is given in three equivalent forms.\newlineWhich form most quickly reveals the y y -intercept?\newlineChoose 11 answer:\newline(A) m(x)=2x2+16x+24 m(x)=2 x^{2}+16 x+24 \newline(B) m(x)=2(x+4)28 m(x)=2(x+4)^{2}-8 \newline(C) m(x)=2(x+6)(x+2 m(x)=2(x+6)(x+2 )\newlineWhat is the y y -intercept?\newliney y -intercept =(0,) =(0, \square)
  1. Definition: The yy-intercept of a function is the point where the graph of the function crosses the yy-axis. This occurs when the input xx is equal to 00. To find the yy-intercept, we need to evaluate the function at x=0x = 0.
  2. Evaluate Option (A): Let's evaluate option (A) m(x)=2x2+16x+24m(x) = 2x^2 + 16x + 24 at x=0x = 0.\newlinem(0)=2(0)2+16(0)+24=0+0+24=24m(0) = 2(0)^2 + 16(0) + 24 = 0 + 0 + 24 = 24\newlineThe y-intercept for option (A) is (0,24)(0, 24).
  3. Evaluate Option (B): Now let's evaluate option (B) m(x)=2(x+4)28m(x) = 2(x + 4)^2 - 8 at x=0x = 0.
    m(0)=2(0+4)28=2(4)28=2(16)8=328=24m(0) = 2(0 + 4)^2 - 8 = 2(4)^2 - 8 = 2(16) - 8 = 32 - 8 = 24
    The y-intercept for option (B) is also (0,24)(0, 24).
  4. Evaluate Option (C): Finally, let's evaluate option (C) m(x)=2(x+6)(x+2)m(x) = 2(x + 6)(x + 2) at x=0x = 0.\newlinem(0)=2(0+6)(0+2)=2(6)(2)=2×12=24m(0) = 2(0 + 6)(0 + 2) = 2(6)(2) = 2 \times 12 = 24\newlineThe y-intercept for option (C) is (0,24)(0, 24) as well.
  5. Comparison: All three options give us the same y-intercept, (0,24)(0, 24). However, the question asks which form most quickly reveals the y-intercept. The standard form (A) m(x)=2x2+16x+24m(x) = 2x^2 + 16x + 24 directly shows the constant term +24+24, which is the y-intercept when x=0x = 0. Therefore, option (A) most quickly reveals the y-intercept without any additional calculations or transformations.
