8 is the answer, because 4 x 8 = 32
Your equation should be 5 - r + 2 = 3.
Answer:
k = 7
Step-by-step explanation:
The given figures are lines f(x) and g(x)
For the line f(x), we have the y-intercept at (0, -3) and slope = (-1 - (-3))/(-3 - 0) = -2/3
Therefore, line f(x) = y - (-3) = -2/3·(x - 0) which gives f(x) = y = -3 - 2·x/3
For the line g(x), the y-intercept is (0, 4), and the slope is (4 - 2)/(0 - 3) = -2/3
The equation of the line g(x) is therefore, g(x) = y - 4 = -2/3·x, which simplifies to the slope and intercept form as g(x) = y = 4 - 2/3·x
Therefore, given that the transformation of f(x) to g(x) is given as g(x) = f(x) + k, we have;
k = g(x) - f(x) = 4 - 2/3·x - (-3 - 2·x/3) = 4 - 2/3·x + 3 + 2·x/3 = 7
∴ k = 7
<h2>♪Answer : </h2>
»f(x) = 7x² - 3x + 7
»f(2) = 7(2)² - 3(2) + 7
»f(2) = 7(4) - 6 + 7
»f(2) = 28 - 6 + 7
»f(2) = 29
»f(-1) = 7(-1)² - 3(-1) + 7
»f(-1) = 7(1) + 3 + 7
»f(-1) = 7 + 3 + 7
»f(-1) = 17
»f(0) = 7(0)² - 3(0) + 7
»f(0) = 7(0) - 0 + 7
»f(0) = 0 - 0 + 7
»f(0) = 7
so, f(2) + f(-1) + f(0) is
