Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4x² + 7x - 18
f(-9) is x = -9
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-9) = 4(-9)² + 7(-9) - 18
- Evaluate Exponents: f(-9) = 4(81) + 7(-9) - 18
- Multiply: f(-9) = 324 - 63 - 18
- Subtract: f(-9) = 261 - 18
- Subtract: f(-9) = 243
The correct answer for this question is "<span>reflect over the y-axis, reflect over the x-axis, rotate 180°." In order to get to the expected transformation, first, flip it over the y-axis which cost 90 degrees of rotation. Then lastly, flip shape from 2nd quadrant over the y-axis. It will now be coincide with the transformation at the 3rd quadrant. Could I be brainlest... I'm a middle schooler who did this so...</span>
Answer:
the 2nd option
Step-by-step explanation:
the second option is in standard form (y = ax^2 + bx + c), c gives us the y intercept
