Explanation:
k(a) = | -2a + 3 | - 1
k(3) = | -2(3) + 3 | - 1 replaced the a with 3
= | -6 + 3 | - 1
= | -3 | - 1
= 3 - 1
= 2
g(x) = 4²ˣ⁻¹ + 7
g(1) = 4²⁽¹⁾⁻¹ + 7 replaced the x with 1
= 4¹ + 7
= 4 + 7
= 11
f(x) = | 8x² - 5x + 3 |
f(-2) = | 8(-2)² - 5(-2) + 3 | replaced the x with -2
= | 8(4) - 10 + 3 |
= | 12 - 10 + 3 |
= | 5 |
= 5
h(x) = -3x + 9
h(-1 + x) = -3(-1 + x) + 9 replaced the x with -1 + x
= 3 - 3x + 9
= 12 - 3x
f(n) = 5n - 1
f(-3n) = 5(-3n) - 1 replaced the n with -3n
= -15n - 1
