The correct answer is: 23

Explanation:

Given function:

f(x) = 3x^2 - 2x + 7 ---- (A)

f(-2) means that we have to put x = -2 in equation (A):

f(-2) = 3(-2)^2 - 2(-2) + 7 \\ f(-2) = 3*4 + 4 + 7 \\ f(-2) = 12+4+7 \\ f(-2) = 23 \\


Hence the correct answer is: f(-2) = 23.

jeyben [28]

Answer:

The answer is C.

Step-by-step explanation:

Multiply 4 by 76, 77, and 78.

4 * 76 = 304

4 * 77 = 308

4 * 78 = 312

304 = 304, so C is the correct answer.

A line passes through (9, –9) and (10, –5).Write an equation for the line in point-slope form.
CaHeK987 [17]
Y - y1 = [-9-(-5)]/[(9-10] * (x - x1)

y - (-9) = [-9 + 5] / [-1] * (x - 9)

y + 9 = (-4) / (-1) * (x - 9)

y + 9 = 4(x - 9)

y + 9 = 4x - 36

y = 4x - 36 - 9

y = 4x - 45  This is the slope - intercept form.

y - 4x + 45 = 0 This is the standard form
