The given function is
A . f(4) means we have to evaluate the function when x = 4.
<h2>Therefore, f(4) = 14.</h2>
B. f(x) = 50 means we have to evaluate the function when y = 50.-
<h2>Therefore, f(16) = 50.</h2>
C. f(-5) means we have to evaluate the function when x = -5.
<h2>Therefore, f(-5) = -13.</h2>
D. f(x) = -34.
<h2>Therefore f(-12) = -34.</h2>
7) • A straight line is 180 deg
• So B = 180-138 = 42 degrees
• Isosceles triangles have equal angles on the equal sides
• So G = 42 degrees
• We know a triangle has 180 degrees
• So 180 - 42 - 42 = 96 degrees for A
8) • Use similar logic to above
• TCB = 180 - 87 = 2x
• TCB = 46.5 degrees
• ACB = 180 - 65 = 2x
• ACB = 57.5 degrees
• TCB + ACB = ACT = 104 degrees
There are 4 terms in the expression.
Terms are each of the entities.
4x, + 3y , -12x, +5
