Step-by-step explanation:
A.
1. f(x) = x⁴ - 7x² + 2x - 6
where x = 1
SUBSTITUTE
f(x) = x⁴ - 7x² + 2x - 6
f(x) = (1)⁴ - 7(1)² + 2(1) - 6
f(x) = 1 - 7(1) + 2 - 6
f(x) = 1 - 7 - 4
f(x) = -6 - 4
f(1) = -10
2. f(x) = 10x³ + 4x² -5
where x = -3
SUBSTITUTE
f(x) = 10x³ + 4x² -5
f(x) = 10(-3)³ + 4(-3)² -5
f(x) = 10(-27) + 4(9) -5
f(x) = -270 + 36 - 5
f(x) = -234 - 5
f(-3) = -239
*evaluating a function simply means to substitute the given value of x / function to the equation
