Given fx 8x15 Find f4 f0 f3x4 f2x1 2fx fx 1fx fx2 ffxSoluti

Given f(x) = 8x-15. Find: f(-4) f(0) f(3x^4) f(2x-1) 2f(x) f(-x) 1/f(x) [f(x)]^2 f[f(x)]

Solution

a-)-32-15 = -47

b-)-15

c-) 24 x⁴ - 15

d-) 8 X (2×-1)-15 = 16×-16 = 16 (×-1)

e-) 2X (8×-15) = 16×-30

f-) 8X (-×)-15 = -8×-15

g-) 1÷(8×-15)

h-) (8×-15)² = (8×)² -2X (8×) X (15) + (15)² =

64ײ - 240× + 225

i-) 8 X (8×-15)-15 = 64×-135
