How do i do transformations

f (x) + b shifts the function b units upward.

f (x) – b shifts the function b units downward.

f (x + b) shifts the function b units to the left.

f (x – b) shifts the function b units to the right.

–f (x) reflects the function in the x-axis (that is, upside-down).

Step-by-step explanation:this is for a computer i dont know what you mean

i can't see the picture : /

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
