Simplify
sin^2x+tan^2x+cos^2x

sec²x

Step-by-step explanation:

sin²x + tan²x + cos²x

sin²x + cos²x + tan²x

1 + tan²x ( sin²x + cos²x = 1 )

sec²x ( 1 + tan²x = sec²x )

Step-by-step explanation:

SIN^2x + tan^2 x + cos^2x

= x( sin^2 + tan^2+cos^2)

=x(1+tan^2)   since sin^2+cos^2 =1

=xsec^2 ( since sec^2 = 1+tan^2)

=sec^2x

boxplot e is the answer

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
