Q. Math (2/2)[+15 Pts]Jika f(x) = 4x² - 9x + 8, maka tentukan nilai f(-5) - f(8)!Rules:- no copas, no a.i!!!- wajib sertakan cara pengerjaan!- ragu? silahkan skip - ngasal hanya untuk cari point = report - bingung? tanyakan - tidak meminta imbalan (b.a, like, ratting dsb)- baca dan pahami terlebih dahulu!GOOD LUCK-!!btw, ada yg masih ingat saya?​

The length is:
the square root of [ (the difference in 'x' values)² + (the difference in 'y' values)² ]
D = √ [ (-2-6)² + (5-2)² ]
= √ [ (-8)² + (3)² ]
= √ (64 + 9) = √75 = 5√3 = 8.66 (rounded to 3 sig-figs)

To find the length of line segment PQ, use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]. Substitute the coordinates of points P and Q into the formula, calculate, and then round to 3 significant figures. Follow the steps outlined for accurate results.

Jawaban:Jika f(x) = 4x² - 9x + 8,maka nilai f(-5) - f(8) = -39Penjelasan dengan langkah-langkah:f(-5) = 4(-5)² - 9(-5) + 8f(-5) = 100 + 45 + 8f(-5) = 153f(8) = 4(8)² - 9(8) + 8f(8) = 256 - 72 + 8f(8) = 192f(-5) - f(8) = 153 - 192f(-5) - f(8) = -39
